| Sony | SLV585HF | RED TINT OR DISTORTED COLOR IN PLAYBACK PICTURE | In Playback and Record the chroma in the picture had a reddishtint and was somewhat noisy. | ||
| Sony | KV13TR10 | INTERMITTENT WHITE PICTURE, REPLACED THE IF BLOCK | Picture would intermittently go white. Found IF block defec-tive. | ||
| Sony | CDPC215 | HIGH PITCH NOISE FROM LINE OUT AND HEADPHONE OUT | Flex cable ref. 6 insulation tears and shorts to chassiscausing a high pitched noise from the line out and headphone outputs. Thedisplay is also irratic. | ||
| Sony | KV13TR24 | INTERMITTENT SOUND, REPLACED THE IF BLOCK | Unit had intermittent sound. Traced problem to IF block. | ||
| Sony | KV19TS20 | SOUND GOES OFF - STAYS ON ONE CHANNEL, REPLACE TUNER | Sound would intermittently go out, also the set would stay onone channel and had distortion in picture. Traced problem to defectivetuner. | ||
| Sony | KV32XBR10 | HIGH PITCHED OSCILLATING SOUND, REPLACED R-527 | High pitched oscillating sound from the set and poor interlacei.e., looks like horizontal line pairing. Waveform at pin 1, A-84 connec-tor was 25Vpp, horizontal amp waveform at pin 11, T-500 FBT was 225Vpphorizontal. Inspection of R-527 revealed it was | ||
| Sony | KV20EXR10 | NO RASTR - NO SOUND, REPLACED R-567 | No raster and no sound. Faint line horizontally rolling fromtop to bottom of screen. | ||
| Sony | KV32XBR15 | CHANNEL CHANGES BY ITSELF, REPLACED IC-1701 | Channels keep changing by themselves. | ||
| Sony | KV32XBR15 | NO PICTURE OR SOUND, REPLACED IC-442, AND IC-443 | Change IC-442 and IC-443. Data line was grounded. Disconnec-ted pin No. 10 (SDT) on both ICs. Set will operate. -HQ COMMENTS: Thank you for your report. Please check the cause of theshort circuit next time and report to us. | ||
