Marca | Modelo (Chassis) | Sintoma | Causa | Solução | Por:![]() |
---|---|---|---|---|---|
Sony | KV28WS2U | No sound, speakers pop out if volume is raised from zero. Audio output from Dolby A1 board at +5v dc. | Lightning damage to this set and connected VCR. Centre/surround amplifier IC shorted blowing IC protector to its negative rail. Both amplifier ICs replaced as a precaution. No damage to Dolby A1 board | ||
Sony | KV-25M80 BG-2 | Dead | 5V Supply Transformer Short | ||
Sony | KVS3432U AE2 | Front led flashing 13 times, HT at first came on at 139V then went to 75V going off etc shuting back down in protection mode | Found R854 open circuit on -15 volt line off line output transformer | ||
Sony | KV2184 | Main fuse blasted | Replace the STR50115, also replace the mains electrolytic capacitor | ||
Sony | FE-1 | No teltext just P100 | This problem was caused by Q405 2SC2412K being s/c | ||
Sony | FE-1 | No power although relay operates main p.s.u inoperative | Check IC606 STRF6654 for failure, also check resistors R659 0.33ohms,3w, R660 0.39ohms,3w, fusible resistor R603 0.1ohms,0.5w and capacitor C625 100uF,25v | ||
Sony | KX27PSI | Almost totally dead. No video or audio whatsoever. Only the clicking sound of two power relays when the set is turned on, and conversely at power down. The green/red lights on the front panel do appear. Repeated failure every 2-3 years. Why ? | An insight into what TV engineers did, after speaking to Sony UK: a 0.47K resistor replaces L656 in line to Q651 B. b 0.33 ohm resistor added between L650 and Q651 E. A resistor also replaces L657. Still lasted only 2 years. Any better ideas ? | ||
Sony | KVA2942U | LED A flashes once, LED B flashes 13 times. | Bad solder joints on field IC1501 on back edge of main PCB | ||
Sony | FE-1 | After about 30 minutes the set goes to standby, the LED flashes and TV starts again. After 1 Minute the TV Displays : Antenna connection failed! | Change IC101 of IF on A-Board. Order Nr. 875946647 | ||
Sony | KV-X2183E BE3B | Not working, Stand-by indicator led flashing 6 times, Power supply ok | The tuner has loose connections, especially the ground points and the two SMD Ic´s | ||
Sony | KV27EXR25 | No power, no raster, relay comes on | Found horizontal trans short | ||
Sony | AE2 | Sound low & distorted when hot | Check -22v & +22v on plug PL505, if either incorrect check R627 27~ goes high in value | ||
Sony | KV28WS2U | OSD volume bar present continuously. No functions available | Front panel tactile switches leaky. Replace same | ||
Sony | KV2032 | Keeps changing channel | Check voltage on D12 if below 4.8V then change | ||
Sony | KV-20VM20 SCC-H16B-A | Would not eject the tape | Replace Elevator activator rack Broken REF# A34 OEM# 9-908-164-01. - UL# 146T - Set MFG. by Goldstar Similar To: Zenith TVR1920 & KV-13VM20 |
