Page 2: Important Safety Notice
SERVICE NOTE: The CRT DAG is not at chassis ground. 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.
Page 3 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. 2.
Page 4: Leakage Current Cold Check
X-RADIATION 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.
Page 5 megohm and 5.2 megohms. When the exposed metal does not have a return path to the chassis, the reading must be infinity. Remove the jumper from the ac line cord. LEAKAGE CURRENT HOT CHECK 1. Do not use an isolation transformer for this test. Plug the completely reassembled receiver directly into the ac outlet.
Page 6 Philips approved type. PARTS REPLACEMENT Many electrical and mechanical parts in Philips television sets have special safety related characteristics. These characteristics are often not evident from visual inspection nor can the protection afforded by them necessarily be obtained by using replacement components rated for higher voltage, wattage, etc.
Page 7 Chassis Identification and Interchangability Chassis Identification An identification label is located on the outside of the cabinet back. The first four characters (25R5) indicate the basic chassis series. The next two numbers (01) identify the total Electronic Package in the Cabinet.

Page 36 Service Adjustment Notes Caution: The RS Chassis incorporates a "HOT" ground system. Always use a separate isolation transformer when applying power to the ex-posed chassis. Service Adjustment Notes: Unless otherwise specified: All service adjustments are "HOT" voltagewise. For maximum safety, ensure the use of properly insulated tools.
Page 37 Adjust R712 to straighten the vertical lines on the left and right sides of the picture. Adjust R714 to remove any trapezoid distortion (tilt) from the vertical lines on the left and right sides of the screen. NOTE: An adjustment of register 80 (Horz Center) in the service test mode may need to done to center the raster properly on the screen before preforming step number 5.
Page 38 Slowly spread the 2-X Pole purity rings to center the Green portion of the screen leaving the same amount of Red on the left side as there is blue on the right. Loosen the Yoke Clamp screws and slide the Yoke back to the point of best Green Purity. Tighten the Yoke Clamp screw slightly so that the Yoke can still be moved with some friction.
