| Marca | Modelo (Chassis) | Sintoma | Causa | Solução | Por: |
|---|---|---|---|---|---|
| Sony | TCK1A | INCORRECT P/N | Listed motor on page 24 of Instruction Manual shows incorrectpart number. | ||
| Sony | TCK1A | CRACK IN PCB | Several units had no indication of record LED in record mode.This is not due to defective record LED. The problem is caused by a breakin plating, on the record LED circuit board. | ||
| Sony | TCK1A | SAME P/N FOR DIFFERENT NUMBERS | The P/N for the record button is the same as REW/FF/PLAY. Itshould have a diferent number, as the original has a red mark on thebutton and the PLAY/FF/REW do not. -HQ COMMENTS: This information can be found in the July 1979 TechnicalDigest on Page 4. | ||
| Sony | TAN88 | DEFECTIVE COMPONENTS ON POWER SUPPLY BOARD | Complaint was intermittent noise in left channel. Speakerrelay would not stay on. Found L-ch waveform at TP1 at B-level, R-chwaveform erratic. | ||
| Sony | TAN88 | BROKEN PCB TRACES | R-ch won't work. | ||
| Sony | TAN8550 | MISSING CONNECTION | DC balance circuit in class A amp board does not function.Due to missing plating in ground line circuit. This in turn supplies DCvoltage on 0 volt line which in turn causes VFET failure. Also I feelthat if the value of RT701 22 kohm DC bias adjustment | ||
| Sony | TAF5A | THERMAL FUSE IN TRANSFORMER | Primary of T503 was found defective. Upon removal andinspection, a thermal fuse was found in series with Pin 1. There was nosign of heat anywhere in the PPS. Jumping the fuse restored operation -a new transformer was ordered. | ||
| Sony | TAF5A | DEFECTIVE D363 | Unit came into FSC with burned R360 and leaky Q352. Staticcheck of other components showed no gross shorts or opens. | ||
| Sony | TAF3A | TRANSISTORS SHORTING TO HEAT SINK | After the output transistors have been replaced, and unit hasplayed, the outputs will go out again. | ||
| Sony | TA4650 | DC BALANCE | DC balance on the speaker outputs is determined by matchingof Q302 and Q303. | ||
| Sony | TA2650 | REPLACEMENT TRANSISTORS ARE IMPROVED | Customer complained of noise with volume control at midposition, standard input levels. | ||
| Sony | TA2650 | SWITCH OUT OF PROPER LOCATION | No audio output on any function - function switch (S1) wafers180 degrees out. | ||
| Sony | STRV55 | LEAD DRESSING NEEDED | Whining noise from processor with no FM signal and muting off. | ||
| Sony | STRV55 | WIRE NUMBERS ARE REVERSED | Incorrect wire number. Numbers #1 and #3 reversed. | ||
| Sony | STRV35 | DEFECTIVE OUTPUTS | The NPN output transistor opened on one channel of each ofthese receivers. No other problems found. |
