| Marca | Modelo (Chassis) | Sintoma | Causa | Solução | Por: |
|---|---|---|---|---|---|
| Sony | KV-21FS100 BA6 | No power, R640 open | Change R640, IC600 and associated electrolytic capacitor | ||
| Sony | KV-M21TU AE1 | Intermittent rolling and loss of luminance, improves as set warms up | Dry joints on tuner / IF board | ||
| Sony | KV20TS20 | Snowy or intermittent picture, makes popping sound | Solder all coils in stand up board and tuner | ||
| Sony | KV21GMR1 MkII | No raster, flyback squeeking | Check the damper diode, in my case it was leaky, also check the electrolytic capacitor connected from the collector of the pin out trans. | ||
| Sony | KV28WS3 AE3 | No sound or picture, in protection after 2 seconds | No 6.5 Volt on G-board. Fuse resistor PS605 is broken on G-board. Cause: bad contacts | ||
| 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 |
