---|---|---|---|---|---|
Sony | KV27TS20 | VERTICAL FOLDOVER IN MIDDLE OF SCREEN, REPLACE R-543 | Unit had foldover in middle of picture vertically. Drivewaveform and feedback waveforms were incorrect. R-543 changed value from27K Ohm to 35K Ohm. Resistor is in the feedback circuit. | ||
Sony | KV27TS20 | NO VIDEO, REPLACE COMB FILTER CM-301 | Unit displayed no video, but had character displays. Hadsound - G2 normal. | ||
Sony | KV27TS20 | PICTURE BOWED IN ON SIDES, REPLACE C-566 | Pin amp and phase control have no effect found open C-566. -HQ COMMENTS: C566/4.7uF 50V is located off D514/pin damper diode. | ||
Sony | KV27TS20 | SHUTDOWN, REPLACE YOKE AND R-578 | Set in shutdown. R-578 dissipated, reading zero on the 27,12, and 9.3 volt lines. | ||
Sony | KV27TS20 | NO RASTER, REPLACE C-574 | No raster - sleep light on and audio is muted. Turning upscreens raster showed retrace and foldover at top of screen. Sprayingvertical section raster would return but retrace still visible and fold-over still present. | ||
Sony | KV27TS20 | HIGH-PITCH SQUEAL, SEE SB TVP0114, 1-451-275-41 | Intermittent squeal from yoke. -HQ COMMENTS: Please replace the yoke using P/N 1-451-275-41. This wascovered in Service Bulletin TVP0114. | ||
Sony | KV27TS20 | RESISTOR R587, DIODE D518 NO SCREEN VOLTAGE | Resistor R587 was found opened, new resistor installed andburned within a few seconds. Found diode D518 at fault, diode measuresgood with meter but is breaking down under voltage. |
