PRODUCT SAFETY NOTICE Many electrical and mechanical parts in this chassis have special safety visual inspections and the protection afforded by them cannot necessarily be obtained by using replacement components rated for higher voltages, wattage, etc. Before replacing any of these components read the parts list in this manual carefully. The use of substitute replacement parts which do not have the same safety characteristics as specified in the parts list may create shock, fire, or other hazards. 1.3. SERVICE NOTES 1. When replacing parts or circuit boards, clamp the lead wires around terminals before soldering. 2. When replacing a high wattage resistor (more than 1W of metal oxide film resistor) in circuit board, keep the resistor about 5mm away from circuit board. 3. Keep wires away from high voltage, high temperature components and sharp edges. 4. Keep wires in their original position so as to reduce interference. 5. Usage of this product please refer to also user's manual. ViewSonic Corporation 3 Confidential - Do Not Copy N2750w-1 2. Service Tool & Equipment Required 1. 2. 3. 4. 5. 6. 7. 8. 9. SIGNAL GEN.

Working Theorem A. A/D converter (PC) The ADC is to convert RGB analog signal to digital signal that scaling chip can acknowledge .The AD9883 is a complete 8-bit 110 MSPS monolithic analog interface optimized for capturing RGB graphic signal, a +3.3V power supply is necessary. Its 110 MSPS encode rate capability and full-power analog Bandwidth 110 MHz supports display resolutions of up to 1280*1024 at 60 Hz. A clamp signal is generated internally or may be provided through the CLAMP input pin .This device is fully programmable via a two-wire serial port. The HSYNC input receives a logic signal and provide the frequency reference for pixel clock generation. The clock generator COAST input may be used to stop synchronizing with HSYNC and continue producing a clock at its present frequency and phase . The CLAMP logic input may be used to define the time during which the input signal is clamped to GND , establishing a black reference. When the Power Down control input is bringing to low, AD9883 is put into a very low power dissipation mode ,all the output buffers are placed in a high-impedance state. B. Video Decoder (video) The t0956 is a hightly integrated NTSC,PAL,and SECAM video decoder support for high quality LCD-TV video applications. With an embedded SDRAM controller, t0956 supports NTSC/PAL chroma and luma separation using a 3-dimensional adaptive comb filter for reducing the cross-luma and cross-chroma artifacts.The frame buffer is also usec for 3D noise reduction circuit that resumes good visual quality when the input signal is a noisy video source The three 9-bits 108-MSPS A/D converters in the t0956 chip can be used for digitalizing RGB from PC or YPbPr component signals as well. Piior to each channel contains the AGC and clamping circuits with paogrammable gain and offset. A total of 10 video input terminals can be configured to combinations of RGB, YPbPr , CVBS, S-Video inputs. The component, composite, or S-Video signals are sampled at a free-run external clock frequency(20~80 MHz). After the video decoder processing, the video data was sent out with a line-locked alignment rate(27 MHz). The t0956 comes with 128-pin C. QFP package. DVI input The SiI169 Receiver uses PanelLink Digital technology to support HDTV and high-resolution digital displays for DTV and PC applications. It features High-bandwidth Digital Content Protection (HDCP) for secure delivery of high-definition video in consurmer electronics products. The SiI160 comes with integrated,pre-programmed HDCP keys, greatly simplifying manufacturing and providing the highest level of security. For improved sase of use, the SiI169 has enhanced jitter tolerancd and low-power standby mode. PanelLink Digital technology is the world’s leading DVI solution D. Scaling controller The t0932 chip is a LCD-TV controller chip for color display up to SXGA or 1400*1050 wide screen panel.It includes a 96/64-bits controller for frame rate conversion and 3D interlace-to progressive video processing. It also supports non-linear scaling for 4:3 to/form 16:9 conversion, flexible picture in video display, cinema to TV conversion, hue/saturation adjustment, and advanced OSD system. The t0932 chip is targeted for the applications of high-end LCD-TV. It will accept all HDTV video signals for flat panel display. It comes with 336-pin and 316-pin BGA package.
