Sony kv-40xbr800 blinks two times


  1. Two blinks - B+ over current protection (OCP), unit goes to the standby mode then displays the 2 blink fault. Could be a short in the power supply of any of the circuits.

My sony kv-40xbr800 blinks 6 times, no video no audio, it wont turn on, whats going on?


The problem is on the 'A' circuit board. It is the IC504.Or, it is a low voltage drop or a short. Replace the "A" board. It is the front board on your right when you are at the rear of the set when you remove the cover. Look it up on the net. PS Don't touch the chassis while it is on...HIGH VOLTAGE !!!

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
