| Marca | Modelo (Chassis) | Sintoma | Causa | Solução | Por: |
|---|---|---|---|---|---|
| Sony | KV32XBR70 | H OUTPUT TRANSISTOR FAIL, REPLACE T501 | H output transistor was running hot. Checked waveform at H output transistor and found ringing in it. | ||
| Sony | KV32XBR70 | TUNER TAKES TOO LONG TO LOCK ON CHANNEL, REPLACED D102 | The tuner took too long to lock on to the channel. Found the H sync input to the CPU IC101/pin 21 to be only 3.8vpp. | ||
| Sony | KV32XBR70 | HOR. OUTPUT FAILURE, SEE SB 161R1 | Dead Hor. Output Q-503 failed. | ||
| Sony | KV32XBR70 | VERTICAL PULLED DOWN, REPLACED C501, D500 | Vertical pulled down voltage on IC500/pin 6 low. | ||
| Sony | KV32XBR70 | BARKHAUSEN OSCILLATION, RESOLDERED FBT CONNECTIONS | We received some reports of barkhausen oscillation which maybe intermittent in nature and sometimes signal strength dependent. Theproblem is caused by a poor ground connection on the focus block sectionof the flyback. | ||
| Sony | KV32XBR70 | GEOMETRIC DISTORTION, ADD ROTATABLE DISK MAGNET | Received several reports from customers complaining about ver-tical/horizontal lines bending in picture. In the above case the top 3lines are bending and all other lines are perfectly straight. You cannotstraighten these lines by conventional methods i | ||
| Sony | KV32XBR70 | RANDOM A/V AND CH SETTINGS/STEREO LIGHT FLASHING, IC-101 | Writing new A/V data in the service mode or from the user re-mote will not be retained. When power on again, A/V settings come up atrandom channel settings not preset. Stereo works but light flashes. Re-placed IC-101 and IC-102 did not help. All else | ||
| Sony | KV32XBR70 | INOPERATIVE SET - NO B+, REPLACE IC-651 | No B+ ran F board with lightbulb load separately. Found+167Vdc on Pin No. 1 of IC-651 and no voltage anywhere else. IC-651 openinternally at collector to emitter of TR-1 inside IC-651. | ||
| Sony | KV32XBR70 | BLANKED PICTURE - LOUD STATIC NOISE, REPLACE S-54 | Power can be turned ON/OFF from front panel only. No otherfunctions. Very loud static noise and no audio. | ||
| Sony | KV32XBR70 | UNIT HAS NO AUDIO, INTERMITTENT VIDEO, REPLACED IC-582 | Unit had no audio in any mode, video was intermittent and onscreen display was displaced to the far right side of the raster. | ||
| Sony | KV32XBR70 | ONLY VIDEO 1, VIDEO 2 AND VIDEO 3 BUTTONS ON RM-762 WORKED | Video 1, 2 and 3 buttons on RM-762 worked on KV-32XBR70 butnothing else worked. On front controls of TV all manual functions worked.D-05 and D-07 checked good but upon replacing unit worked. | ||
| Sony | KV32XBR70 | ANODE CONNECTOR MISSING, 1-540-006-32 | When replacing the A board, the anode wire from the flybackis missing. Is there a part number for it? -HQ COMMENTS: Please order the Anode Cable, part number 1-540-006-32.Future boards will come with the anode Cable. | ||
| Sony | KV32XBR70 | BLANKED HORIZONTAL LINES IN PICTURE, REPLACE D1514 AND R527 | Picture looks like horizontal lines are being blanked out ran-domly. Also heard a high pitched noise from around yoke but yoke is good. | ||
| Sony | KV32XBR70 | HAS HV, NO PIX, NO SOUND, REPLACE IC-444 | When unit was plugged in, set would turn on itself. It wouldhave high voltage but no picture and no sound. You could not control any-thing including power ON/OFF. The unit was in micro lock-up. | ||
| Sony | KV32XBR70 | SET GOES INTO OVP INTERMITTENTLY ON TURN ON, REPLACED Q-651 | Set goes into OVP intermittently on turn on (every 4 or 5times). When unit works, all voltages are correct. |
