You are absolutel | ||
| Sony | TCFX120 | CAPSTAN WASHER | FPR L1559 suggests using part number 7-623-921-01. This willnot work. -HQ COMMENTS: If this does not work, use original washer. There haveonly been two reports of this symptom. | ||

| Sony | KPR46DX10 | MICRO LOCKED UP, NO FUNCTIONS, REPLACED D-012 | Set was on, had high voltage and raster but no sound or videoand no functions would respond. There was no vertical pulse at pin 4,IC-001. I found D-012 shorted. | ||
| Sony | XR7180 | PH-11 AND PH-12 ARE BOTH IMCOMPATIBLE WITH REPLACEMENT PARTS | The beveled corner on PH-11 and 12 is at pin 1 instead of thenormal pin 2. The real PCB layout is also different than in the servicemanual. I could not find replacements for PH-11 and 12. I have a sampleif you need it. | ||
| Sony | CCDF30 | DEAD UNIT | F-991 blown. Found short across IC-005 SS-86 pins 2 and 3.Further checks revealed that C-059 was shorted. This is the third CCD-F30I have seen with this problem. | ||
| Sony | STRAV1020 | UNIT IN PROTECT MODE | Unit was in Protect Mode. IC-731 was found shorted and wasreplaced. This did not restore operation. The protect circuittransistors, Q-721, Q-722 and Q-723 were also all shorted. | ||
| Sony | KV27XBR15 | NO VIDEO,SOUND AND CHARACTER DISPLAY OK, FLUX IC-1103 | Demonstration mode indicates PIP ok, except no parent or childvideo. IC-301 on A board has inputs but no RGB outputs except dis-play pulses. DC voltages on C board ok. IC-301/25 IK waveform normal.IC-301/15 (YS input) measured 2.5 Vdc not 0 Vdc, YS sh | ||
| Sony | STRD2010 | NO DISPLAY OR SOUND | Unit has no display and will not respond to power switch. | ||
