Re: KDF-55W655

Red light blinks in 5 times then pause and then repeats. It is the lamp error. " Lamp Driver Defect"
When the "LAMP-PORT" (pin 95) is low, the lamp is not turned on. If the "LAMP-HV-DET"(pin 96) is low at the same time, it is classified as no high voltage of the lamp driver. I'm guessing it needs a Lamp driver which I think is on the C Board, which is part of the "Optics Unit Block Assy. The C Board cannot be orderd separately, and Optics Unit Blocks are not cheap. Good luck

I have a Sony KDF-55WF655 and the bulb blew out and I smelled something electrical burning.

3 blinks is indicating that the lamp door cover isnt making contact so the lamp door cover is either attached wrong or the switch is defective.

Sony tv model kdf 50e2000 shuts off and red light blinks 3 times.

You need to open up set and clean out all fans of dust or the new bulb isnt being cooled, or the color lcd isnt being cooled shutting TV off.

Red Light Flashes twice KDF-E50A10

Are you putting the lamp cover back in place before trying to turn the set on? The 2 blink error is a temperature error you might want to check the thermal sensor, is your lamp door warped?

Problem for Sony Grand WEGA KDF-55WF655. Hello,

5 times Red LED blinks means Lamp Driver Error. (KDF-55WF655)
2 possible reasons, either Lamp is gone or Ballast Supply got bad.
Replace lamp first, in most cases it solved the problem.
How old is this TV and did you replaced lamp recently?

4 blinks shows problem either one or all 4 fans are not working AND internal temperature high error.

If you are familiar with TV repair and know basic electronics then unplug TV from AC outlet an take off back cover and check fans are running?

No Picture - Lamp Indicator Blinking

This may be the main power supply, or the lamp supply. This is providing that the new lamp is okay.

The service tech will swap out the modules to service the set.

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

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,

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.
