| Marca | Modelo (Chassis) | Sintoma | Causa | Solução | Por: |
|---|---|---|---|---|---|
| Sony | BE3 series FE series RE2 series | Test Mode entering | With TV in st/by use R/C press "OSD" Key, followed by "5", followed by "Volume +", & finally "TV" key,(blank box).TV should power up upon pressing last key, and display "TT - -". | ||
| Sony | BE3 KV28FX20U | Dead - faulty parts in stanby psu | IC5605 TNY253P pt no 8-759-584-19, R5602 4R7 1/4w, pt no 1-249-389-11 | ||
| Sony | BE3 | LED flashes 13 times - no sound/pic | No tuner activity to micro - removed tuner & resoldered most conns | ||
| Sony | BE3 | Dead - no led flashes - eht briefly flashes | LOPTx - HR7337 fits | ||
| Sony | BE3 | De sensitising the trip cct | 1k resistor from D618 cathode to deck enabled the set to work normally including the protection stages | ||
| Sony | BE-2A KVM2151U | pic flashing B&W and lines on pic | DJ on LOPTx earth connection | ||
| 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 | BE-2A KVM2101U | E-W error, width control not working properly | C806 47nF 250V (113618711) | ||
| Sony | BE2A KVM2101U | E/W slightly bowed & excess width | C806 47nF 250v in E/W diode mod cct |
