| Marca | Modelo (Chassis) | Sintoma | Causa | Solução | Por: |
|---|---|---|---|---|---|
| Sony | KV1913 | NO SOUND | Sound goes on and off, cooling C226 would confirm problem. | ||
| Sony | KV1746R | SHUT DOWN, INSTALLED C547 AS PER T/N | This unit would intermittently go into HV shutdown. | ||
| Sony | KV2644R | INCORRECT TUNING, REPLACED IC2002 | Set would stay in address position A at all times. I foundwhen I turned channel set switch on and programmed set, it would work OK.But if I shut the set off, and turned it back on again, it would come onin position A and could not be addressed again. | ||
| Sony | KV2643R | NO OPERATION, REPLACED C539, C805 AND R812 | Set inoperative. Found R812 open and C805 leaky. Replacedthem and picture displayed vertical bar (approx. 5 inches) on left side,R812 was running warm. Found C539 open. | ||
| Sony | KV1945RS | POOR REMOTE OPERATION, REPLACED IC1, CX-786 IN COMMANDER | Poor sensitivity with remote approx. 6 feet. | ||
| Sony | KV1945RS | SHUT DOWN, SELECTED R563 | This unit intermittently shuts off, sometimes twice a week,sometimes once. Voltage on Pin 12 was 5.3V making it too near thethreshold level of 5.6V, changing R563 to satisfy the procedure in manualresults in a 15K resistor which was half of the original | ||
| Sony | KV1945R | NO COLOR, REPLACED IC501 | No color. Found no pulse at Pin 20 of IC301. Traced theproblem to Pin 22 of IC501 where I found no sync out. | ||
| Sony | KV1217 | DEAD, REPLACED Q602 | No sound, no picture, channel indicator stays in one position,tuning and band indicators are dim. Found regulator transistor Q602leaky, and both audio output transistors Q205 and Q206 shorted also R232open. | ||
| Sony | KV2647R | SNOW PICTURE, RESOLDER R053 | Set displayed snow on all channels. I found R053 on MF boardimproperly soldered. | ||
| Sony | KV2647R | SET WOULD NOT TURN ON/OFF BY REMOTE, IC-101 | Set would not turn on/off. | ||
| Sony | KV2645RS | COLOR DISTORTION, REPLACED R751 | Bleeding color (red). Found R751/470kohm resistor changedvalue. | ||
| Sony | KV2643R | RASTER PULSATING, REPLACED R609 | Picture and raster pulsating. The 135V line exhibited samepulsation. | ||
| Sony | KV2145R | NO PICTURE, FBT | Set kept shorting out the horizontal output transistor. | ||
| Sony | KV2101 | PICTURE DISTORTION | Set had light vertical bands in picture. They started on theleft and became less bright as you moved to the right. Horizontal outputwaveform was affected as well. | ||
| Sony | KV1946R | PICTURE DISTORTION, REPLACED C524 | Set would go into vertical bounce after warm-up. |
