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 0.33Ω resistor added between l650 and q651 e. a resistor also replaces l657. still lasted only 2 years. any better ideas ? | ||
