Possible failure in the main board as the power supply and the microprocessor is working fine.
The processor indicates the errror in the system as this can be very much speculative.
But it iwll be good to take a first hand look inside than to list a whole lot of possibilities. Check for visible damages, for capacitors leaks, for resistors open or for short in semiconductors.

Phillips tv no pic no sound just flashing light


Its not going to be a do it yourself repair--likely a bad board or even boards--have a repair center (authorized for this brand) inspect it.

Just getting a set like this apart safely is tricky.

I have tried to turn my television on and the status light blinks for about a minute, you can hear the TV try to start up and then the whole system shuts down without anything actually powering up. Also...


Unplug the tv for about a minute - plug it in and press the reset button on the front of the tv - hold it until the light blinks. The set should come on in a minute of two - if not try the same routine again.

UNPLUG TV AND THEN PLUG BACK IN---TURN ON---GREEN POWER LIGHT COMES ON FOR A MOMENT AND GOES OFF.

PRESS AND HOLD “device” and “menu” buttons on front of tv for at least 5 seconds and then release both together.


Watch for power light to blink in a sequence:

1 blink-then 2 blinks-------no error

2 blink-then 1 blink-------X-ray protection

2 blink-then 2 blink-------SHORT PROTECTION*******

2 blink-then 3 blink---------deflection circuit problem

2 blink-then 4 blink---------vertical circuit problem


******2, then 2 is most common---usually means one of the fuses that protect the Convergence IC or IC’s is blown---set will detect no voltage to convergence IC and shut down.


SET WILL REPEAT BLINK ERROR CODE UP TO 5 TIMES AND THEN TO GET IT TO REPEAT MORE YOU HAVE TO UNPLUG SET AND TRY TO TURN ON AGAIN.


IF IT IS 2 AND THEN 2---USUALLY
CONVERGENCE CIRCUIT PROBLEM

if it is 2,2 I have start to finish instructions for this repair in this model.

Sony KDF-50E2000 shuts down and blinks repeatedly twice.


The 2 blink error is a temperature error and the 6 blink error is a thermal fuse error. You may need to unplug the set and get you a can of canned air, take off the back lower cover and blow out all of the fans inside the set.

Had a power outage while watching tv. Then 3 blinking lights.


This is an on-going problem with DLP sets. Normally you shut the set off and the cooling fan cools the lamp down and then it shuts off. In your case, of which it's not your fault, however your lamp has taken a major hit by not properly cooling down, in turn, you need to replace your lamp at this time.
I suggest in the future if you have an electrical storm and a chance of a power outage while your watching tv, I would'nt play that model or any other model of a DLP set.

Our 52" widescreen LCD TV just quit working.


This set uses a lamp ( not picture tubes ) The part # is TS-CL110U. Almost certainly it is bad. They are easily obtainable and you can easily change it yourself.

Blue screen and shut off by self


You will need to reset the Netcommand and tuner settings in the set. The little indented button in the front of the set needs to be pushed in (when the set is off). The front light will blink for about a minute or minute and a half. Then, reprogram the Netcommand settings. This should solve your problem. If you need more information, then, reply to this post and I will respond.
