| Marca | Modelo (Chassis) | Sintoma | Causa | Solução | Por: |
|---|---|---|---|---|---|
| SONY | BE2A | Problemas OSD: em operação normal: SEM OSD em AV : OSD éra quase imperceptível / sempre que o OSD éra "chamado" toda a imagem ficava Vermelha | R812 1K 1W e diodo D806 RGP02-17, visto o RGP02-17 ser dificíl de encontrar, usei o diodo retificador BY448 1500V 2A, funciona perfeitamente | CesarM | |
| Sony | KV-M21_ _ Chassi BE2A | Cor de início OK. Passado 3 a 4 min. pisca e chega a desaparecer | TDA8304 | ||
| Sony | KV-M1400 BE2A | Insuficient vertical deflection. Line rolling on top of picture | Replace ceramic capacitor C524 | ||
| 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 | KVM2141 BE2A | Screen graphics only - ok feeding another set from scart | digital transistor Q005 type DTA143TK | ||
| Sony | BE2A KVM2151U | Dead with psu blow up | IC601 STR54041 chopper chip (use genuine), Q601 BC637-16, R601 3R3 10w, R611 120k & F601 | ||
| Sony | BE2A KVM2151U | Arcing LOPTx effect on pic with accompanying sounds | C606 in psu dry joint | ||
| Sony | BE2A KVM2151 | Int shut down with 300v present on chopper chip | Change STR power chip | ||
| Sony | BE2A KVM2141U | Fading pic | C021 22µ 50v ( read ok out of cct) | ||
| Sony | BE2A KVM2140UB | Pic & sound fade off aft prolonged use | Check / replace light blue caps C821 100µ 16v & C823 22µ 50v also C021 22µ 50v near jungle chip also check sm res below it for corrosion | ||
| Sony | BE2A KVM2140 | Sound drops & pic dims aft an hour | Q005 DTA143TK sm on print side of pcb coll dropped to 2.5v (11.7v) - Tr faulty | ||
| Sony | BE2A KVM2140 | picture faded over several hours & the sound level reduced too.When changing the volume, also adjust brightness. | usually caused by Q005 (2SA1162-G or 2SA 1037K). This device reads high resistance when tested & needs checking on the ohms time 100 scale of the AVO. In my set this SM transistor was OK. The fault at length was traced to C012 22mfd 50v which was leaking through the PC & had damaged SM resistor R045 47K along with a piece of print running it. All SM parts in this area had to be removed & the PCB cleaned up & bridged where the acid had damaged the print. | ||
| Sony | BE2A KVM2101U | E/W slightly bowed & excess width | C806 47nF 250v in E/W diode mod cct | ||
| Sony | BE2A KVM1420U | Pic & sound fades aft 15 mins | Adj vol increases contrast - C012 22µ leaked causing damage to Q005 DTA143TK & R045 47k sm | ||
| Sony | BE2A KVM1420U | Snowy pic with noisy sound | SAWF SWF101 |
