---|---|---|---|---|---|
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 | ||
Sony | KV1221R | NO ON/OFF FUNCTION, REPLACED RL001 | Unit would not shut down manually or on remote. Whenattempting to turn off set with manual switch or remote, the sound wouldmute, but the raster would remain. Tapped on the case of relay RL001.Power immediately went off. Found RL001 was hanging up due | ||
Sony | KV1216 | PICTURE PULLING HORIZONTALLY, REPLACED IC201 | Picture pulling horizontally on some channels. Problemtraced to output of sync separator, Q301, where horizontal sync amplitudewas lower than normal. Observing composite video at Pin 14 of IC201showed horizontal sync pulse to be just slightly higher th | ||
Sony | KP7220 | PICTURE DISTORTION | Set had about 8 inch overscan. Found set-up cord was18 inches too long. | ||
Sony | KP7220 | INSUFFICIENT VERT HEIGHT, REPLACED C5521 | Insufficient vertical height on all three CRTs: about 3inches short top and bottom of the screen. Found vertical sawtooth atbase of Q5510 (on DA board) reading 2.4Vpp, should have read 3Vpp. |
