SAFETY PRECAUTIONS
!! Important Safety Notice !!
Many electrical and mechanical parts in this chassis have special safety-related characteristics. These parts are identified by in the Schematic Diagram and Replacement Parts List. It is essential that these special safety parts should be replaced with the same components as recommended in this manual to prevent Shock, Fire, or other Hazards. Do not modify the original design without permission of manufacturer.
Leakage Current Hot Check (See below Figure) Plug the AC cord directly into the AC outlet. Do not use a line Isolation Transformer during this check. Connect 1.5K/10watt resistor in parallel with a 0.15uF capacitor between a known good earth ground (Water Pipe, Conduit, etc.) and the exposed metallic parts. Measure the AC voltage across the resistor using AC voltmeter with 1000 ohms/volt or more sensitivity. Reverse plug of the AC cord into the AC outlet and repeat AC voltage measurements for each exposed metallic part. Any voltage measured must not exceed 0.75 volt RMS, which is, corresponds to 0.5mA. In case any measurement is out of the limits specified, there is possibility of shock hazard and the set must be checked and repaired before it is returned to the customer.

SERVICING PRECAUTIONS
CAUTION!! Before servicing receivers covered by this service manual, read and follow the SAFETY PRECAUTIONS on page 2 of this publication. General Servicing Precautions 1.Always unplug the receiver AC power cord from AC power source before; Removing or reinstalling any component, circuit board module or any other receiver assembly. Disconnecting or reconnecting any receiver electrical plug or other electrical connection. Connecting a test substitute in parallel with an electrolytic capacitor in the receiver. CAUTION!! A wrong part substitution or incorrect polarity installation of electrolytic capacitors may result in an explosion harzard. 2.Do not spray chemicals on or near this receiver or any of its assemblies. 3.Do not defect any plug/socket voltage interlocks with which receivers covered by this service manual might be equipped. 4.Always connect the test receiver ground lead to the receiver chassis ground before connecting the test receiver positive lead. Always remove the test receiver ground lead last. 5.Do not connect the test fixture ground strap to power supply heatsink in this receiver Electrostatically Sensitive(ES) Devices Some semiconductor(solid state) devices can be damaged easily by static electricity. Such components commonly are called Electrostatically Sensitive(ES) Device.Examples Circuit Board Foil Repair Excessive heat applied to the copper foil of any printed circuit board will weaken the adhesive that bonds the foil to the circuit board causing the foil th separate from or "lift-off" the board. The following guidelines and procedures should be flollowed whenever this condition is encountered. At IC Connections To repair a defective copper pattern at IC connections use the following procedure to install a jumper wire on the copper pattern side of the circuit board.(Use this technique only on IC connections.) 1.Carefully remove the damaged copper pattern with a sharp knife. (Remove only as much copper as absolutely necessary.) 2.Carefully scratch away the solder resist and acrylic coating(if used) from the end of the remaining coopper pattern. 3.Bend a small "U" in one end of a small guage jumper wire and carefully crimp it around the IC pin. 4.Route the jumper wire along the path of the out-away copper pattern and let it overlap the previously scraped end of the good copper pattern. Solder the overlapped area and clip off any excess jumper wire.

1) Description Most flat-panel monitors and projectors require a digital graphics input in order to accurately scale and display graphics. The huge installed base of computers with analog video graphics interfaces necessitates the use of a graphics digitizer to re-digitize the analog RGB signal before further processing. The MST9883CR is a fully integrated analog interface for digitizing high-resolution RGB graphics signals from PC's and workstations. With a sampling rate capability of up to 140 MHz, it can accurately support display resolutions up to 1280x1024 (SXGA) at 75 Hz. The clamped input circuits provide sufficient band width to accurately digitize each pixel. The MST9883CR provides a high performance highly integrated solution to support the digitization process, including the ADC's, a voltage reference, a PLL to generate the pixel sampling clock from HSYNC, clamping circuits, and programmable offset and gain circuits to provide brightness and contrast controls. When the COAST signal is asserted, the PLL will maintain its output frequency when HSYNC pulses are absent, such as during the VSYNC period in some systems. A 32-step programmable phase adjustment control (0-360 deg) is provided for the pixel sampling clock to adjust for the difference between the HSYNC edge and RGB pixel edge timing. The MST9883CR can send output data through one 24-bit port at the pixel clock rate. The MST9883CR can also support RGB to YCbCr conversion. The MST9883CR has internal programmable pattern generator for testing. The MST9883CR can accept either standard TTL, CMOS levels or sawtooth vertical deflection signals for VSYNC input.
