You have the famous regulator problem, or the bad regulator problem, or the cold solder connectioin is on or around the flyback transformer.

SOURCE: my sony standbt light is on. no pitcure

The "D" board has probably failed. Most of those boards are not available from Sony but can be sent to Sony for Refurbishing. The 'D" Board has the Deflection , Protect, and most of the PowerSupply incorporated on it. Most of those Boards are also Double Print/Multi Layered style boards that make it difficult to repair at a component level.
Best thing to do in mt opinion is to call Sony at 100222SONY and see if they can refer a Service Facility to you if you are willing to put 600.00 to 800.00 into it.
Hope this helps,

  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.

I have a Sony kv-40xbr800. The standby light flashes 6-7 times and does not turn on. If left off for a couple of day, it may turn on. Is there an easy fix?


SIX Blinks---No Horizontal (H STOP), no raster, goes to the blinking selfdiagnosis
function immediately. Check C515 & 516 and the jungle IC, IC206.

SEVEN Blinks---High voltage shutdown. The high voltage has exceeded 33k
and the unit goes immediately into safety shutdown. Check power supply
regulation and horizontal circuits.

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
