Sony KDF-42WE655 Power Supply shot after 4 years

I am told the power supply needs to be replaced on my TV for $500.00. This after the optical block had to be replaced. Is this a common Sony problem?
Might be my last Sony Purchase

    Last night it went off for no reason. When I turned it back on the green power light flashed 4 times then it flashed red 3 times.

    I called Sony and they gave me an authorized repairman. He came out and the red light flashed 6 times instead of 3.

    They said that usually mans the thermal fuse and possibly the fan. If that was the problem parts were quoted at $100.00, labor $295.00. I paid $85.00 for the pick up and delivery already.

    They called and said the power supply was bad and had to be replaced. Part $150.00, labor again $295.00.

    Any info you can provide is helpful.

    Thank you

    Lamp door was not warped and has never been open. I did look at it.

    It is not a fan but a power supply he wants to replace.

    I am dubious also

    Thank you for your time. I really appreciate your input

    I had the optical block replaced about 6 months ago. Free thanks to my circuit city plan but now I have the same issue. For no reason the red LED blinks and keeps blinking indicating something is wrong again. This is the worst POS Tv I have ever owned!! I'll let you all know what the repair is this time once I get the right people to come out. CC sends the ticket to a company that doesn't service my area, then I call and get it sent to the local company. Last repair if I had paid would ahve been $1,100.00!!!

    Your information is puzzling. The original 3 flash code means that the lamp door was not completely closed. The following 6 flash is likely a bad thermal fuse. But first, did you notice if the lamp door was warped or melted in any way? This is very important.

    I have repaired many of this model and have yet to replace a power supply. Can you tell me the symptoms? What was the original reason that you called for service?

  • jfgte8296 May 11, 2010

    Oh and my red LED is blinking 10 times. Not sure is that means something but it should.

    the power supply unit cost about $175-$180 /so he's charging about $300-$320 for labor

    Ok I read this wrong. They didn't do the thermal fuse and fan? They just said they thought that was it. I'm wondering if they are talking about the main power supply. a 6 flash CAN mean a power supply failure, either a G1 or G2 failure. What probably happened is that they checked the thermal fuse and found it OK (the thermal fuse is the most common cause of a 6 flash failure), so then they checked the power supply. You've already had the optical block replaced (I assume that was under warranty) so the TV should be in pretty good shape once you get done. This is a tough call; I understand your position about feeling like you are throwing good money after bad. All I can tel you this is a good TV and it's unusual for the power supply to fail, but not out of the question.

    Also, FYI, it would help to know which fan the repairman wants to replace. I'm getting a bad feeling about the quote they gave you. Please answer the question about the lamp door first.

I have a KDF 42WE655..while watching tv, I heard a popping sound.


If the lamp is blowing that soon, the cooling fan is not working, or is plugged with dust. I have heard some people have a filter that needs changing or cleaning. Check your manual. The cooling fan is on the optical block and not easy to get to.
Probably a job for a tech.

Please help-question about sony optical blocks


Talk to Sony about the blue blob issue, they may still replace the optical block for free.

If not, fix the blinking light TV.

Blink Codes
3X - Lamp cover not installed correctly, usually after lamp change, or cover detect switch is bad.
4X - Check fans (one or more failed to pass RPM test during power on diagnostics)
5X - Lamp ballast (power supply)
6X - Usually the thermal fuse - usually from inadequate air flow (fans dusty)

All other codes usually require a trained technician to diagnose and repair.
