| Marca | Modelo (Chassis) | Sintoma | Causa | Solução | Por: |
|---|---|---|---|---|---|
| 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. | ||
| Sony | KV1945RS | SNOW PICTURE, REPLACED PRESCALER | Snow on all channels. No output from prescaler. | ||
| Sony | KV1945R | SOUND AND PICTURE DISTORTION, REPLACED IC005 | Volume and picture levels go down. One could adjust volumeand picture levels in UP mode, but a few seconds later, the levels wouldgo down to minimum. | ||
| Sony | KV1945R | INTERMITTENT ON/OFF, LEAKY D026 | Intermittent on/off. Last channel memory is off. When turnmaster switch on, TV comes on intermittently. IC006 Pin 11 is low (2.4V)should be 5.1V. D026 zener didoe was leaky. | ||
| Sony | KV1913 | VCR PB PICTURE DISTORTION | Viewing TV normally, off channel no problem set looks good,however, when VCR played through set, top of picture would curve to rightlike flag waving. VHS system is what customer has and complained on.However, distributor put Betamax through unit and sam |
