Try cleaning your air filter sounds like its a thermal problem, often its due to an obstruction in the air filter.

TV turns itself off, then on automaticlly


The fan should run for a few minutes after shut off to cool the lamp down.

If I read and understand correctly somewhere in the cycle you are getting 5 red blinks? that is an error code........

Either you or I can Google the model number of the set with 5 blinks.....or visit the Sony site to see what it means.....

Well my mom was watching tv and it just shut off so then my mom turned it back on thinking she might have hit the power button accidentally. But when she turns it on it started blinking the green light for...


The flashing light red power light should only stay while the fan cool down for about 1 minute after a power off (remember to always wait before unplugging the TV so the lamp can cool down with the fan). Does that flashing start right away after plugging back the TV after an hour of letting it without AC power.

The red light should flash no longer than 10 sec. This prepare the light to be turned on. If all is OK the green should stay (no longer flashing) and the sound and picture come on.

As for the lamp flashing, i bet it's only 1 time each 5 sec? Or do it group many rapid flash each 5 sec?

Things that can be wrong:
-the fan lamp

-the lamp is not proprely inserted (wait an hour before manipulating it to be sure it cooled down, and use glove to not put body oil on it).

-Lamps is defective and is not operating properly so you can't get to the usual on screen message that recommend to change the lamp.

I have a 60' sony wega r60xbr1 i just had a new light engine installed last night the tv was never turned on afterwards . I turned it on the screen come on shut off imediatly the red led flashes 4 times...


LOOK IF YOURS IS A SONY I had a sony grand wega 60 inch with the same problem as many tv turns on shuts off the red led FLASHED 4 TIMES. it is a heating issue if one of the three fans inside are not turning when the tv is on even on the first few seconds of turning it on the tv will send a fault code of four flashes . Then the tv shuts off so it wont burn its self up or damage the optical block. all with this same problem of 4 flashes take a flashlite and make sure your fans are turning if not that is your 4 flash problem. I hope this helps someone and if it does i have done my job .

TV won't turn on. Flashes RED 4 times... shuts off


On this particular set 4 blinks can be either a fan error or a temperature error. Unplug the set and take the back off and see if the fans are running and also check to see if the lamp door might be warped. If the fans are running you probably need a thermal sensor.

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?
Thanks.

SONY GRAND WEGA KF-50WE610 can't turn on TV screen.


Ths 5 blinks usually indicate an AKB problem. There is a break in the video path. I'll look up your specific model and post the results here. Please update this if you wish to attempt the repair yourself.

Thanks,

Sony KDF-50WE655 will not power up. Red blight blinks 4 times


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?
