G'Day!

Unfortunately, what you're describing is a repair issue. You won't be able to address the problem with troubleshooting. There is a part inside the TV that needs to be replaced. If you're under warranty, this will cost you nothing. If you're not under warranty the cost will likely be a minimum of $200 parts and labor. However, be warned that the cost could be considerably higher.


I hope I've provided you useful assistance and that this information allows you to make an informed decision as to how to proceed from here. Please be sure to vote on my response. I hope I've earned a good rating from you today.

Please post a comment if you need additional assistance so that I can help you further.

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.....

Pana TH-52PWD8UK. No picture, flashing red LED on front panel


Thanks for the quick answer. I purchased the set in 2005 and it lives outside under an overhang on my patio in humid South Florida. Unfortunately, I couldnt count the red flashes before it went completely dead. Think it was 4or 5. This would correspond with a possible fuse failure on the Power supply. I bought the online service manual, I just wish I knew what to do with it!! The fuses both seem to check out ok on a continuity check. any ideas? Thanks, Charlie

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.

TV does not turn on. Stand By LED blinks 4 times and pauses and blinks 4 times again Tv will not turn on...when plugged in the red stand by light flashes 4 times...you can hear the tv turn on but a black...


On older Sony, sometimes a power surge causes the set to be in shut down mode. Try unplugging for 5 minutes and then plug in and try. This many times will fix.

Standby LED flashes red 4 times with pause then 4 times


You either have a bad fan or one of the rotation sensors mounted on one of the fans has failed. Take the back off the set and see it the main fan slightly right of center is rotating. If it is, there are two more fans, one mounted right above the lamp and another on the optical block itself. You will have to pull the optical block to check those.

Green flashes then tv turns off


or a new lamp. you could first replace the lamp.
the screen might work fine for a couple of seconds, but then it fades away or deteriorates. This means the lamp is going bad.

Sony projection big screen


does the led flash when you try to power it up? If so let me know the number of flashes. From your description I would suggest 1 of 2 things happened. (1) The Convergence amp ICs have shorted and blown the 5 amp fuse on the G board, or (2) the red CRT has shorted shutting the set down. Check the fuse and if blown replace the fuse and disconnect the Red CRT PC board from the RED CRT and try powering up the set. If it powers up without shutting down then unplug the set and rehook the RED crt pc board and try again if it shuts down the reds shorted. But if it still wont start with the CRT unhooked or blows the fuse Change the Convergence ICs

Dead set press power button you hear the relay and you see red led flash 3 times and stops? Has no HV or other action. Tech removed the back as no 200 volt supply, did unplug CN706 and now has 200volts. Tech did remove the IC702 and same it comes up so needs this IC.

Flashing LED
<< Back to Quick Fixes Page
If your set all of a sudden won't come on, e.g., the screen is blank, but the LED on the under the screen next to the on/off switch keeps flashing, then there may be an internal fault on the set that needs to be reset.
To force the reset, try this:
  • Unplug the set and wait a few seconds
  • Replug and see if the video returns
Whenever the set senses an internal fault through its monitoring circuitry, it essentially shuts down the set. The flashing LED provides the indication that a fault has been detected. Removing power to the set resets the monitoring circuitry. When plugged back in, the circuitry again does a check of the system. If it finds that there truly is a problem, then the set is shut down and the LED will again flash.
