SOURCE: TV not working

the symptom is usually caused by a breakdown in the power supply circuit. in most modern receivers (transistorized and/or ic), it may also be caused by a breakdown in the horizontal deflection circuits (hor. oscillator, pre-drive, or drive circuits). supply voltages for the tuner, video if,sound if, and vertical output are usually supplied by the horizontal output circuit. but if you doesnt know anything about these stuffs, better bring it to a qualified service tecnhician.

SOURCE: 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

Check 470 uF 450 V in the power supply. I don't know if the chassis is the AE-5, but I had a similar case and the capacitor was bad.

Please tell me if it worked.

SOURCE: my 32'' sony wega blinks 5 times

The 5 blinks means a problem in the set's AKB (auto kine-bias) circuit. Sony TV's monitor the operation of the picture tube. When some kind of trouble has been detected, the TV blanks the screen and flashes the 5 blink error code. This may be due to problems in the video circuit, a bad picture tube, or adjustments that have changed due to aging of parts. There isn't anything I can suggest you try on your own to fix it. Because several things may cause the problem, and the proper tools and service information needed to troubleshoot, you should refer this repair to a professional.

My Sony Trintron's LED Light blinks 9 times when I try to turn on the set


  1. If it is intermittent 9 blinks, meaning sometimes the TV comes on and other times you get flashing, then change the switching regulator on the "G" board or check connections. Make sure the regulator is -12 or -13 (negative). If you wish to get more details about the blinking codes to Sony brand TVs, check this link. Pull up older posts there.

Sony wega kdf42we655 power led blinking red


If lamp light is on at tv front then replace lamp as existing lamp sounds dead/ broken.
Lamp replacement procedure would be written in user manual of tv.
And if lamp light is not on but standby light is blinking then let me know how many times it is blinking to find out problem cause as standby light blinking is an error code.
