| 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 | ||
