Sony KV34XBR800 Won't Turn On

TV is 5 years old. Never had a single problem. This AM TV won't turn on. Standby light blinks 7 times. Assuming this is a power supply issue what am I looking at in terms of repair costs?

Re: Sony KV34XBR800 Won't Turn On

Is this your TV's problem? - about a 5 year old KV-34XBR800 suddenly won't power up - yet sometimes will still power up if left alone for a little while. For a possible fix to your Sony KV-34XBR800, go here
for my post #108 woth a step-by-step solution including pictures. $21.83 is all it cost me and 3 hours is all it took, though I was also taking the time to photograph and document the repair. I fixed my own TV as many others on that forum have. Feel free to contact me at if you run into difficulties. Please don't discard that set - It's one of the best sets Sony has made, according to lots of people online.
P.S. This fix will also work with some other KV series TV's with the same problem.

Sony tv won't turn on, light in standby blink three times

that is a master control board failiure, it is caused by having your TV on all the time, when the TV gets warm, you need to shut it off and let it cool down(that caused your problem) call sony and order a replacement part, it will take you about 20-40 minutes to install yourself.

TV Turns self off- 4 blinks on standby light

Yes, the blinks are error codes. I would not bother trying to figure out what they mean, I can tell you right now. Expensive repair. Average repair costs are 1/4 to 1/2 of the TV's current worth. Most likely a bad transistor. The average expected life span of a TV set is 3-5 years. After that, stuff starts wearing out fast. Time to move on.

Sony FD Trinitron WEGA Won't Turn On

The key here is the count of the blinks. I'm assuming that the model number is KV-36FS120. Please post the blink count. It should be a count-pause-count...

TV will not come on.

The 7 blinks indicate a high voltage shutdown (high voltage exceeded 33,000V). This is usually caused by a defective regulator. Could you please post the exact model number (KVxxx) and I'll look up the part you will likely need?

Blinking Standby Light

KV32hs500 tv won't turn on. Standby light blinks 7 times, stops and then 7 more times, etc.. The tv will usually come on after about 2 hours or so of being off. Plays fine when on but once it gets turned off the problem happens again. Any suggestions? T.V. is 5 years old.
I have a similar problem . mine blinks 6 times or 7 sometimes also,and comes on with sound ,no picture for about 2 seconds then shuts off. Anything?
