| Make | Model Ch. | Symptom | Problem Solution | Solution | By: |
|---|---|---|---|---|---|
| Sony | KV1412 | Set reverts to standby mode when switched on, because IC003 does not reset correctly | Replace IC003 on A board, IC type CX523013P | ||
| Sony | KV1412 | Vertical line at the left of the picture | Replace L506 on A board, replacement part number 1-407-366-00 | ||
| Sony | KV1412 | Noisy picture | Replace relay RY481 on S2 board | ||
| Sony | KV2020 | Picture is folded over at the top and curled at the top left hand side | Replace C559 and C560 | ||
| Sony | KV25K5U FE1/FE1A | No sound or vision, front led flashing | Replaced line output transistor, resoldered dry joints on driver transformer. Also check for any other poor joints in this section. Have used a 2SD1878 as replacement, This seems to work ok as the Sony original is very expensive | ||
| Sony | KV-HF14M80 BG-3S SSC-U21F | Dead in standby mode, no primary voltages, led orange | Change uMICOM CXP86449-627S | ||
| Sony | KVD-C21MF1 SCC-K68A-A | No sound and screen not appearing, B+ ok | No input on pin 5 of IC301 MC44002P, R339 had failed, once replaced the unit was ok | ||
| Sony | KV-2565MT SCC-E64P | Horizontal output transistor Q802 goes short repeatedly | C818 1uF, 250v had lost capacity, replaced C818 and Q802 and unit was ok | ||
| Sony | KV-M1400D BE-2A | Dead, after replacing ic601 STR54041 and Q601 BC637 standby led blinks red twice, then blank, no HV | Replace fuse p801 ICPN15 - 0.6A 50V, TO92 | ||
| Sony | KV-M1400D BE2A | Retrace lines on picture, 60V on RGB transistors | C700 100nF, 250V seems to be leaky, but main problem is R723 which had gone from 27R to 1.2M, both on CRT board | ||
| Sony | KV27TS20 | Intermittent video or snow | Resolder points A, B, C, D in tuner PCB, check cold solder on tuner shield 2-106-349-21 | ||
| Sony | KV32TS20 | Dead, good tip that I always use to save changed parts after replacing Q502, Q601, Q602 and blown fuse 602 | I hook up 100 watt light bulb across fuse conection, then turn on tv, if light is very bright you still have a short. You saved the parts you changed, light should be dim and or blinks | ||
| Sony | KV32TS20 | Dead no click, Q502, Q601, Q602 shorted and blown fuse 602 | Change all the above parts and also check R647, C512, C525, D607, D608, D609, D610, D622, VDR601 off primary side of T605. I`ve also found T605 bad too. ToughDog, Sony has bulletin out on this model | ||
| Sony | BE3D | Procedure to enter the service mode | Press standby, i, 5, vol+ and tv TT should now be displayed on the screen indicating the set is in the service mode | ||
| Sony | SLV-E800 | No picture - screen is empty. Sound is ok | Check IC101 BA7630F, if video signal comes to input pin 1 but not present at output pin 14 then replace this IC | ||
| Sony | KV2565 | Dead with H. output short circuit, replacment blows short again | First check power area and repair dry joints then change all high voltage PF value capacitors in the horizontal section, this fixed the problem | ||
| Sony | KV-M2131U BE1 | Intermittent loss of syncronisation, both horizontal and vertical | The surface mounted power transistor on the teletext module requires resoldering. As there is evidence of scorching on the board the use of a more substantial component would be indicated perhaps with small heatsink | ||
| Sony | AE1 | Field non linearity and short picture | Check / replace C531 680uF, 25v, only slightly leaky, but a new one cured the fault | ||
| SONY | KV34FV310 | Zoom automático | R8091-470K | ||
| Sony | KV-1483 | Não liga | Q 503 em curto |
