DP-6X THINGS YOUR SHOULD KNOW
(01) ATSC Reception problems:
Important information to gather when encountering a customer with ATSC reception problems. Please
gather all information listed below before calling for Technical Assistance.
(See below for contact information).
1. Make sure we are dealing with ATSC reception issues only, please.
2. Model and serial number...By the way, we are placing ALL model and serial
numbers on the front right hand side of the units.
3. Did the customer run auto programming? Please run auto programming again just in case.
4. Signal strength on this channel? Available through customer menu.
5. What kind of antenna are they using? Rabbit Ears? Roof antenna? Are they using antenna rotor? Cable?
6. What is the Software version? This is available through the customer menu.
7. What channel is having the problem? Digital channels are a main channel and a sub channel, always
displayed as : 25-1 or 25-2 and 25-3, 25-4, etc,.
Please ask for all sub channels available, sometimes there are more than one or two.
8. Do they know it's respective channel on analog format (NTSC)? Is the analog channel coming in ok?
Just to give you an example:
San Diego channel 8 NTSC is equal to channel 25-1 ATSC, when you do auto programming, you will
see 8-1 on TV OSD, but you can also enter: 25-1 and you will also get to the same 8-1 digital channel.
We all must be very familiar with this fact in order to see if we can select the channel directly, without
the need to do auto programming. See www.transmitter.com for state by state listing of analog/digital
equivalency table, their location and their power.
9. What is the stream reception format? You will see: 480i, 480p, 720p or 1080i on the upper section of the
OSD when receiving.
10. What is the Channel content? Is this ABC, CBS, PBS? And station identification is needed, like WYCN
TV Channel 5 or whatever.
11. Try to contacted the Local Station? Explain the problem to the engineer. They may be able to investigate
and make some corrections. If you did speak to someone at the station, whom did you talk to? Name and
phone number or e-mail address?
12. Local stations are starting to provide a feedback for their customers mostly through a web page....They
always want to know if customer are receiving the Digital Channels and are always looking forward to
get feedback.
13. Try PIP and make sure the PIP channel is also the same channel as the one they are trying to receive
with Ant C.
14. Describe problem and if possible, send a picture/drawing or a video.
15. Is sound OK?
16. Customer name and phone numbers, please.
Once this information is gathered, please contact Hitachi Technical support (see below) and provide all
information gathered.
Phone: 800-393-2369 (Authorized Servicers only)
Phone: 619-591-5352 (Non-Authorized Servicers only)

(02) Lead Free Solder beginning in 2004.
2004 product will use lead free solder (unleaded) to help preserve the environment. Please read these instructions
before attempting any soldering work.
Caution: Always wear safety glasses to prevent fumes or molten solder from getting into the eyes. Lead free
solder can splatter at high temperatures (140 degrees F) .
Lead free solder indicator
Printed circuit boards using lead free solder are engraved with an "F".
Properties of lead free solder
The melting point of lead free solder is 104 ~ 122 degrees F. higher than leaded solder.
Servicing solder
Solder with an alloy composition of Sn-3.0Ag-0.5Cu or Sn-0.7Cu is recommended.
Although servicing with leaded solder is possible, there are a few precautions that have to be taken. (Not taking
these precautions may cause the solder to not harden properly, and lead to consequent malfunctions.)
Precautions when using leaded solder
Remove all lead free solder from soldered joints when replacing components.
If leaded solder should be added to existing lead free joints, mix in the leaded solder thoroughly after the lead
free solder has been completely melted (do not apply the soldering iron without solder).
Servicing soldering iron
A soldering iron with a temperature setting capability (temperature control function) is recommended.
The melting point of lead free solder is higher than leaded solder. Use a soldering iron that maintains a high
stable temperature (large heat capacity), and that allows temperature adjustment according to the part being
serviced, to avoid poor servicing performance.
Recommended soldering iron:
Soldering iron with temperature control function (temperature range: 320-450 degrees F .
Recommended temperature range per part:

(03) Fan Part # GS00821: In Digital Module
• The Fan Runs all the time. This is normal.
• All sets with a Digital Module (ATSC Tuner) has a Fan.
• The below chassis utilizes a Digital Module which contains many sophisticated circuits.
A cooling fan is utilized in all Digital Modules (ATSC). It is normal for the customer to hear air
circulating and the fan running if the room is quiet. This can be compared to a computer
cooling fan as they are very similar. The customer may not be aware of the fact that his or her projection
television has a cooling fan incorporated. Please educate the customer with this
information. Do not assume that just because the customer can hear the fan that there is a problem with
the fan. Only if the fan produces a grinding or ticking sound should it be
considered to be defective.
• These Fans are running ALL the time. This is NORMAL operation. These applies to ALL Hitachi units
with an integrated ATSC tuner.
• This is, is getting to be a very important issue for all our customers. Remember, one huge difference
between their previous TV sets and any of these NEW Digital Models is the fact that their previous TVs
never had a fan...therefore, there was no fan noise at all!
• Now, once they notice the fan noise, some of them do not like it. First thing they do is: They call for service.
Many Technicians MAY NOT be familiar with these units, therefore, they can not tell if the noise is actually
normal or too noisy!
(Continued on page 3)

DP-6X THINGS YOUR SHOULD KNOW
•
•
Replacing the fan just to see if the noise goes away or to reduce it is just too much work and it will be for
nothing....then the Customers will be disappointed to find out the noise is still there (after any of the fans/
modules/or even complete TV sets were replaced). But once they hear the explanation related to the REASON why they hear this noise, they always understand.
New Technology requires the use of faster processors, these processors require the use of cooling fans. Although minimal, these fans do make noise when they are running, this is "normal" operation noise.
(04) CRT- I need to Change All Three CRTs, what to do?
In a situation where it becomes necessary to replace all three CRTs, it may not be as big a job as first considered.
There are many times in which if a couple of First steps are followed, the job may be very easy thanks to Magic
Focus.
IMPORTANT: You must find the reason for the CRT burn ( if this is the reason for replacing all three CRTs at
once), before installing the new CRTs. Look for Deflection collapse caused by poor solder connections on the
Yoke Plugs, Convergence Yoke Plugs, Vertical Output IC, Drive Transformer and/or Flyback. Make sure the H
and V Sweep Loss circuit is functioning. Make sure the Yoke plugs are seated properly. Clean all Spark Gaps.
Pry off the caps on top of each spark gap and clean the contacts with a thin, fine sand paper. Reinstall the caps.
Solder all interconnections between the Signal PWB and the Deflection PWB.
THINGS TO REMEMBER:
• If at least one of the defectives CRTs is properly set up (in relationship to geometry) then it can be used as a
guide for setting up the new CRTs. This means you have checked that the Center is in dead center and that
the lines running left to right and top to bottom are straight and all the grids are linear.
•
•
•
Magic Focus will be your biggest friend in the process.
If at all possible, do not remove all three defective CRTs at once. Leave the best adjusted CRT in place until
the other two new ones have been installed and aligned.
You most likely will not need an Overlay unless the set is already a mess related to geometry.
HERE IS THE PROCESS:
• After receiving the new CRTs, first determine which of the defective CRTs is best aligned. (This doesn't
matter which color). For our discussion we will say it's the Red.
• Remove the Defective Green CRT.
• Install the New Green CRT.
• Clear the RAM. (With Power Off, press and hold the Service Only switch. The press the Power Button on
the Front Panel). Set will come on with cleared RAM. No Convergence Correction.
• Loosen the Yoke on the New Green CRT and rotate it until it matches the Defective Red Vertically and
Horizontally (TILT) while looking only at the center. Don't worry if the Center isn't aligned with the Red.
After adjusting the Tilt, tighten the Yoke.
• Run a string from the top left corner to the bottom right corner.
• Run a string from the top right corner to the bottom left corner.
(This will give you a center mark where the strings cross.)
• Now, using the centering magnet for Green, adjust Green to the center mark where the two strings cross.
Remember that the RAM has been cleared. In this condition the Red is to the Left of Dead Center and the
Blue is to the Right of Dead Center. This is normal.
• Now, Power Off the set. Then turn it back on. This will restore the previous Convergence stored data. If you
checked the Red centering before all of this began, (Item 1 under Things To Remember above), then the new
Green CRT and defective Red CRT centers should now match.
• Run Magic Focus. This should now return the set to proper Convergence or at least very close where only a
minor touch up should be required. You can do this touch up now or wait and do it after all three CRTs has
been replaced.
Now, do the same thing with the New Blue CRT starting with step (2) above.

IMPORTANT NOTE:
Are you aware that HDTV/SDTV Channels that are shown On Screen may not be the actual channel numbers
that you would press on the TV remote control to tune that specific channel?
In other words, what you see on the PTV Screen is called VIRTUAL CHANNEL. As and example, to receive
(8-1) in San Diego (with out running auto programming in a DTV ) you will actually need to tune to channel 55.
Because UHF channel 55 is were they are receiving the Digital Virtual channel 8-1. The Virtual Channel information is embedded within the data received is the Virtual Channel ID. This was decided because the Customer
will know that the HDTV channel they are watching will be a known channel in their area. This will help them to
recognize the channel of origin.
Below is an excellent web site to visit. This can be a tool that will help you KNOW what the actual channel is
when you are going to randomly select them by remote control number keys. You can just select it without a
need to run auto programming (on most units ~ with exception of the WXW prior to software upgrade).

(08) Using HDMI and a Cable Box, some HD signals give an Error Message:
ERROR NOTICE:
HDMI Interface with some Cable Boxes.
When selecting some HD Channels, the notice reads as follows:
"The HD content protection on your display has been compromised. Please use the Y Pb/Pr Outputs for your
HD connection". Or "Monitor Does not support HDCP" or “Lower Resolution” or “Snow”.
The warning will show up at power on and will remain there if left alone.
EXPLANATION:
"This is not a problem with the Projection Television".
With the addition of Digital transmission, many avenues of private digital data and usage privileges are being
incorporated into the transmission stream. During this age of HD infancy, these codes are being manipulated
and can generate this situation. HDCP is the issue here. Please contact your local cable operator for additional
information. A temporary work-around is to disconnect and reconnect the HDMI cable between your cable box
and TV. Your patience is appreciated until this issue can be resolved by the cable operator. NOTE: Both the TV
and the Set Top Box Must Be ON.

(09) Using the Cutoff Adjustment to check for a bad CRT.
• Symptoms: (Also See Item 11 below for Spark Gap problems)
• Color Temperature changes.
• Picture Flickers.
• Brightness fluctuations.
Did you know that you can check for a defective CRT (internal grid shortage) by looking closely at
the single horizontal line while in the Cut-Off adjustment mode?
In this mode, the Vertical is collapsed so the Service Technician can adjust the Cut-Off level of
each CRT. (Note: This determines the Life Span of the CRT. If this adjustment is too bright, the
Tube Life is shortened).
PROCEDURE:
•
Enter the I2C Service Menu and Select the SERVICE adjustment by using the cursor down and
then press cursor right. Vertical will collapse.
•
While looking at the single colored line, look at any color to see if it's blinking or flickering. If it
is, the CRT needs to be replaced. The Room should almost dark to make the line easier to
see. You may have to turn the Screens up slightly to see the line more clearly. Remember, the
line should be just barely visible.
•
If a Color can't be turned completely off, this too indicates a defective CRT and can quickly
identify when CRT is bad.
•
Replace the defective CRT.
(Note: This isn't related to the Digital Convergence Grid. The Cursor (adjustment point) will blink in
this mode and this is normal).
(10) Picture Dark, abnormal, Changing Color Temperature.
•
Clean the Spark Gaps on each CRT PWB. Remove the Cap, clean the contacts with thin
fine sand paper, blow out, reseal.
(11) POD (Cable Card) Possible Problems
1: Make sure software is current version: (See the Web Site to confirm current version).
2: If after inserting the Cable Card, the unit IDENTIFIES the Cable Card and goes on to provide a
notice as to how to start Service or it just starts receiving the approved programming.
If all this goes on, it is obvious that card and the host (receiver) have established what is commonly
known as the "Handshake" and all is Normal.
If for any reason, this does not happen, and the "Handshake" does not occur, there still may not be a
problem.
Try leaving the Card inserted for a longer period of time.
If this seems to take too long, insert the card just before retiring for the evening. Leave the Card inserted over night. Set does not have to be on.
There are many reasons that the Card may take an extremely long time to initiate the handshake function. This could be due to traffic, server issues, etc... Please make sure to follow these steps first before considering the Cable Card as being defective.
If after an overnight attempt has failed to initialize the Card, then most likely there is a problem with the
Cable Card itself. Please get a different or a new Cable Card to try
again.

(12) Lip Sync Issues:
This is a news letter written by an engineer at KFMB in San Diego. It explains the cause and things
that may help when a problem of "Lip Sync" is encountered.
KFMB Digital TV Newsletter
Number 19 . January 19, 2003
READ MY LIPS
The HDTV forums have been abuzz about poor lip sync on several local HDTV channels. This is potentially a real nightmare for
digital broadcasters, and I'll take a little time here to explain why, and what you can do about it.
By definition, lip synchronization is another way of saying that the audio portion of a TV program matches in timing the video
portion.
In the good old days, this simply meant that the lower loop of film on the projector was not of the right size because your projector slipped a few sprockets and you would just reach over and adjust it during the next break.
In about 1980, video synchronizers started showing up at TV stations that allowed us to use special effects with sources that
were of a completely different timing, like remote news vehicles and networks from outside the station. Without those synchronizers, fading or special effects would just look like a mess on-air. However, they introduced a problem: they delayed video without
delaying audio. This wasn't much of a problem for a single frame of delay because few people can detect it. But add a couple of
frames for network processing and complex effects, and suddenly you have visible lip sync problems. Audio delay units were
introduced, but few stations used them. KFMB used a monaural one until we went stereo in 1990. When the Audio Engineering
Society (AES) defined digital audio in the early 1990s, they seemingly forgot to deal with synchronizing audio with video. There
are no clues built into the AES audio stream for where a given audio frame is in time with respect to an accompanying video
stream. There's no chance of having automatic lip sync. Fast-Forward to 1999 We open a new all-digital master control and
disk drive servers to replace tape-delivered programming and commercials.
Some sources have ways to adjust audio timing, and some don't. Now we have a digital transmitter and an analog one. When
producing the news, we find that the more complex a video effect is, the more video delay we have, with real lip sync issues
when carrying the video from several remote sites on the screen at the same time. We build a box that tells our new audio synchronizer/converter to delay a given amount depending on the combination of sources used. The box works well.
In 2001, we open a new all-digital production control that fixes the variable delay problem. Life is good, but intermittent problems
with lip sync still show up. Software bugs and corrupt data occasionally plague the station's digital encoder. Remote satellite
sources still have lip sync issues at their source left for us to solve on the fly. In late 2002, our digital stream is added to the
local cable companies. Since there's zero transmission loss, they use our on-air signal for a redistribution medium. However,
they have to re-encode the signal in order to get the correct channel information, program guide, and 256-QAM modulation
scheme, thereby introducing another potential source of lip sync problems. As digital viewers, you too can introduce your own
problems:
You are at the mercy of electronics designers as to how much audio or video delay they introduce.
If you use analog cables to transfer audio between your receiver or set-top box (STB) and your audio amplifier/processor, you
have a digital-to-analog converter at the STB and an analog-to-digital converter at the processor/amplifier, each introducing audio delay, whether a little or a lot.
If you have acoustic effects chosen on your amplifier, you may introduce more delay.
If your receiver/STB gets corrupt data or becomes otherwise confused, it can introduce delay by mistake.
What's a Mother to Do? First of all, make sure you have a problem. We evaluate for lip sync watching for speech in which the
on-camera person moves his or his lips to annunciate plosive "B" and "P" sounds. Be careful that you're not seeing it on a poorly
dubbed single commercial or program. We're going to ask you to be forgiving when there may be a temporary problem with a
hastily organized satellite remote news story--bad things happen in the field sometimes. If you encounter disturbing lip sync
problems, answer a few questions before you ask for help:
Does the problem exist on all over-the-air, cable, and satellite channels? If so, you surely have a local problem. Try resetting
your receiver/STB and processor/amp by unplugging for a few seconds and then plugging back in.
What is the source? Does the problem exist with all commercials, programs, and live news? Note this to help the person you
complain to.
When did the problem begin?
Have you checked the enthusiast forums to see if others have the same problems? A nice website for San Diegans is
http://hdtv.forsandiego.com.
Have you reset your receiver and lip sync is still an issue on all channels? You should contact the cable company in order to
determine whether the problem is with you, them, or their sources.
Does the problem exist on only one channel? Call the provider (cable or DBS) or the source channel. Each will have to analyze
the source and determine the source of the problem. At most stations, they have access to view their own sources, line output
signal, analog air signal, digital air signal, and Time Warner cable analog and digital signals. We count on Cox Cable to evaluate
our signals on their system.

DP-6X THINGS YOUR SHOULD KNOW
(Continued from previous page)
(13) What equipment can I use to generate an HD signal?
• Please see our web site at the following address;
• http://www.hitachiserviceusa.com/Service/Seminars/DP4X-Web/09-things-toknow/16_HD_Gen.htm
(14) Some VGA to Component Adaptors can cause No Picture or Sync Problems.
• Some Set Top Boxes do not have Component Outputs. They have VGA outputs. In this case,
a VGA to Component adaptor will be needed. Some of these adaptors can cause a problem if
they do not have Tri-Level sync outputs.
• They may cause other problems as well, like Horizontal Shift or unstable pictures.
• Please remove the VGA to Component adaptor and test the Component inputs by using a
Component generator directly into the Component inputs to verify.
• Please see the VGA to Component adaptor recommendations on the HD Generator suggestion page.
Note: If a Component Source isn't readily available, use Composite Video input into
the "Y" jack. Insert a dummy RCA jack into the "Pr" plug to force the set into the Component Mode.
The signal will be black and white, but the picture content (other than color problems) can be checked.
(15) POD (CableCARD) no longer works after Memory Initialize or some parts replaced.
• The CableCARD will no longer work after replacing the Digital Module.
• The CableCARD will no longer work after replacing the Signal PWB with the Digital
Module.
When the Customer first receives their Cable Card, they must insert the card and have it authenticated
by the Cable company. Then the customer must call the Cable company with the Host ID information.
After this, the Cable company then sends out data that provides the Cable card with channel mapping
and the allowable channels for this particular customer to view.
• If a Factory Reset is preformed, the Cable Card is no longer authenticated and the customer must repeat the process of re-authentication.
• If a Memory Initialization is preformed, the Cable Card is no longer authenticated and the
customer must repeat the process of re-authentication.
• If the Digital Module is replaced, the Cable Card is no longer authenticated and the customer must repeat the process of re-authentication.
• If the Signal PWB with the Digital Module is replaced, the Cable Card is no longer authenticated and the customer must repeat the process of re-authentication.
(16) POD (Cable Card) Problems, Digital Tuner Problems.
POSSIBLE CORRECTION:
• Be sure to check for the Current Software Version.
• Check the Web Site for Current Software Version number.
(17) What is the Size of the Allen Wrench for removing the Split Cabinet Screws?
•
4 mm
(18) HDMI Doesn't Work
Please clean the HDMI input contacts with Isopropyl Alcohol using a stiff thin brush.
• Symptom -Using HDMI connection, black picture with NO SYNC OSD.
• Sometimes contaminants can cause poor connections on the DVI and/or
HDMI inputs. Cleaning these contacts will eliminate the problem.

(20) Losing Channels on 1/2 of the PinP Window (Analog Half)
• Most often noticed when using a Cable Card.
If the Cable service provider decides that they are going to all Digital Channels, then our TVs, will lose
ALL or most channels on the Analog Tuner side. The Channels they lose will be the ones that are Digital (QAM). Only the Analog channels will remain, if any.
There is nothing wrong with your TV set.
Please note that this set is using One Analog and One Digital tuner. Every time we use PinP and the
2nd tuner is selected as the Sub picture, the Sub picture can ONLY BE ANALOG (NTSC).
DETAILS:
As Cable Companies modernize, they are approaching a Digital solution. This improves picture performance even on the lower resolution signals and helps to minimize transmission loses. It also improves band performance. These Cable companies provide a "Set Top Box" (Cable Box) to receive
and decode these digital broadcast. So as it stands right now, the Cable companies can be broadcasting Analog (NTSC), Digital NTSC (QAM) and SD/HD Digital (QAM). Note: QAM (Quadrature Amplitude
Modulation). If the Customer is using a Cable Box, then they do not notice a problem, since the Cable
Box only outputs one channel at a time..
If the Customer decides to hook the Cable directly into the set and bypass using a Cable Box, then issues arise that may appear to be a problem. Sets which include an HD Tuner will receive ATSC (over
the air SD/HD digital broadcast) and QAM (Cable digital broadcast). The Analog (NTSC) tuner will only
receive NTSC analog broadcast signals.
Most Customer's who decide to hook Cable directly into the set, will in turn most often decide on using
a CableCard application. This will allow the set to receive the Channel Mapping (what channels are
broadcast on what frequencies) from the Cable company so their channel selection will match the
Channel listings provided by the Cable company.
So when they now try to activate PinP and have the Sub picture selected on the Analog tuner, there
will be only a few channels available, if any. These will be the NTSC channels only.
Many Servicers are trying to "fix" these problems....After replacing many parts, they end up exactly at
the same place. PIP with CableCARD will not be getting most channels on the one side using the Analog Tuner. There is nothing wrong with your TV set.
