Page 13 of 15 multiple LCD cells is used. Since a single panel is used, it is necessary to scan the panel with the primary colors to obtain a color picture. A LCD is a light valve which allows more or less light through it, depending on the applied voltage.
Page 15
Regardless of the format of the input, the LCD displays the picture in a 1280x720 format. The Philips LCOS projector uses a single LCD device. To obtain a color picture, the LCD is scanned with strips of Red, Green, and Blue light. The strips of color are developed by splitting the light from the Lamp...

Page 15 of 15 and directing it to three color filters which produce Red, Green, and Blue light. The output from the filters is directed to three rotating Prisms to produce the color strips and direct it to the correct part of the LCD. Data is directed to the LCD in such a way that the correct data for color illuminating that portion of the LCD will be displayed.

Error code definition In case of non-intermittent faults, clear the error buffer before starting the repair. Make sure “old” error codes are not present. If possible check the entire content of the error buffers. In some situations an error code is only the result of another error code (and not the actual cause). Note: A fault in the protection detection circuitry can also lead to a protection.

GENERAL SAFETY NOTES IMPORTANT SAFETY NOTICE Proper service and repair is important to the safe, reliable operation of all Philips Consumer Electronics Company** equipment. The service procedures recommended by Philips and described in this service manual are effective methods of performing service operations. Some of these service operations require the use of tools specially designed for the purpose.
Page 236
PARTS REPLACEMENT FIRE AND SHOCK HAZARD 1. Be sure all components are positioned in such a way as to avoid the possibility of adjacent component shorts. This is especially important on those chassis which are transported to and from the service shop.
Page 237
1. Be sure procedures and instructions to all your service personnel cover the subject of X-radiation. Potential sources of X-rays in TV receivers are the picture tube and the high voltage circuits. The basic precaution which must be exercised is to keep the high voltage at the factory recommended level. 2.
Page 238
LEAKAGE CURRENT HOT CHECK 1. Do not use an isolation transformer for this test. Plug the completely reassembled receiver directly into the ac outlet. 1.5k, 1OW resistor 0.15uF. capacitor 2. Connect a paralleled by a between each exposed good earth ground metallic cabinet part and a such as a water pipe, as shown below.

X-RADIATION PICTURE TUBE REPLACEMENT PARTS REPLACEMENT WARNING Before removing the CRT anode cap, turn the unit OFF and short the HIGH VOLTAGE to the CRT DAG ground. SERVICE NOTE: The CRT DAG is not at chassis ground. TV-VCR COMBI SAFETY NOTES IMPORTANT SAFETY PRECAUTIONS Prior to shipment from the factory, our products are strictly inspected for recognized product safety and electrical codes of the countries in which they are to be sold.

d. X-Radiation and High Voltage Limits - Because the picture tube is the primary potential source of X-radiation in solid-state TV receivers, it is specially constructed to prohibit X-radiation emissions. For continued X-radiation protection, the replacement picture tube must be the same type as the original.

thermally hot parts, c. the ac supply, d. high voltage, and e. antenna wiring. Always inspect in all areas for pinched, out of place, or frayed wiring. Check ac power cord for damage. 7. Components, parts, and/or wiring that appear to have overheated or are otherwise damaged should be replaced with components, parts, or wiring that meet original specifications.

2) Strip about 15 mm of the insulation from the ends of the wires. If the wires are stranded, twist the strands to avoid frayed conductors. 3) Align the lengths of the wires to be connected. Insert the wires fully into the connector. 4) Use the crimping tool to crimp the metal sleeve at the center position.

PREVENTION OF ELECTROSTATIC DISCHARGE (ESD) Some semiconductor solid state devices can be damaged easily by static electricity. Such components commonly are called Electrostatically Sensitive (ES) Devices, Examples of typical ES devices are integrated circuits and some field-effect transistors and semiconductor "chip" components. The following techniques should be used to help reduce the incidence of component damage caused by electrostatic discharge (ESD).
