Question about Sony Grand WEGA KDF-55WF655 36" Rear Projection HDTV

3 Answers

TV turned off by itself and now blinks red led 6 times

I have a Sony grand wega KDF 55W655 and thought the bulb burnt out because of the red blinking light, so i changed it and the tv still doesn't work. That didn't change the 6 flashes of the red led on the power/standby light at all. Can you please give me any advice on what to do next. I would sure appreciate it.

    Tv went darker last night and this morning all I got was a constant blinking red light under lamp.  Do I simply need to change the lamp?  I have a 55 inch - same model

    I have the same exact problem, happened 2 days ago. I find it funny that at least 5 of the exact same tv's went out in about 1 week. Has anyone out there found out yet how to fix this "low B error", and how much did it cost?

    TV will come on with green lights and about 4 sylables can be heard of a program - then no sound and the red light starts blinking in 4's. This has been going on for about 6 months. At first we were running the dust buster over the fan vent covers in the back - not sure why - but it worked and the TV would come on. Now we are up to using canned air, which also works but the red blink attacks are getting more frequent.

    We have the same problem. We replaced the bulb 2 months ago and now the tv continues to shut off and go on standby for about 10 -15 seconds before powering back up and this happens about every 7-10 minutes.

    Any suggestions?

6 blinks means a low B error. Which is no DD 6volt output on G1 board . This will cause no picture and no sound. To fix this yourself you would need the manual to get the correct sequence to test and proper part to order. You can get a service manual for 10.99 at the following link and they will ask if you'd like it emailed to you after purchase. Here is the link,

After replacing the bulb and the tv still didn't work, I then replaced the thermal fuse and that fixed it. The thermal fuse costed about $12.00 and is basically a wire that wraps around the bulb housing to prevent the bulb from overheating. Fortunately the local sony repair shop had one in stock. I figure the dust had built up inside the tv and prevented the cooling fan from circulating the air properly around the bulb housing. Hopes this helps..

6 blinking red lights

You still have your guessed problem. 6 blinks means Low B+ error (power supply). This can be caused by an open thermal fuse, loading by another circuit board, or the power supply itself.

in this set 3 blinks means lamp cover not set properly but i think that your problem is your 6x red blinks that means you have a problem in the audio section in your set(missing a voltage) or a themal fuse open.

Sony LCD television will not power on.

I get 5 blinking red lights for about a minute or so before it powers back down. The Sony TV has a specific light that i presume is supposed to light up when the bulb is out. I'm unsure if this is what it is.
no picture, no sound. tries to boot with green light blinking a few times. then goes to red blinking light, six in all, then waits a few moments, then another 6 blinking red light.
Bulb was already replaced several months ago but we do have the TV on for long periods of time.
