Sony Wega 40" TV will not turn on, standby light blinks 6 times repeatedly

Hello,For model KV-40XBR800,

Pls check following area.

Low HV Shutdown:
On the D Board.
Check IC8004/pin 7 should be 7.4v.
Check IC8006/pin 2 should be 2.5v if lower will trigger shutdown by causing pin 1 to turn on.
Check IC8006/pin 3 reference voltage 2.2v.
IC8006/pin 1 normally at 0v. If high
turns D5007 ON which turns the latch circuit Q6532,
Q6530, and Q6527 ON and turns the AC relay RY6501 OFF.

And NOTE: 6 blinks also can be Low B+ protection.

Unregulated 7.5 v from the power supply to 5v reg IC504 on the A Board. 5v to M Board Q2314

to CPU IC2300/pin 43. If 5v missing set will shutdown with 6 blinks.

Good Luck

Sony Trinitron Wega kv-36fs120 wont turn on, standby/timer LED flashes 9 times.

The relay is in the power supply area. I am sure that the fault is not the relay.

It is very common that there are various components starting to go off spec from age. Most of the failures are in the scan amplifiers and power supply areas.

It is also possible that the CRT emission is too low from age. What happens is that it is on the minimum edge and this explains why the set may turn on some of the time.

When the main uPC in the set sees any potential fault conditions it will go in to a protection mode to prevent damage and to be safe. Your set is probably borderline to operate.

Considering the age of your set, I would be shopping for a new TV set.
