I think your problem requires a call to the manufacturer. My sony tv was blinging 4x and I noticed that I was losing picture. I thought perhaps a short or cable problem, but when I called sony the number of blinks indicated a picture tube that was going to blow. I did not wait I said good bye to a good television and purchased a new one as the repair would cost more than a new TV. You might be luckier 2 blinks could indicate something else. Good Luck!

PT-53WX53G still shutting off-3 blinks


have you checked the 2.2 ohm 2watt resistors? If the led blinks three times the resistors will almost always have at least one that will be blown and need replacement.

PT-47WX53G wont turn on 3 blinking lights from the power area.


If the red power LED is blinking 3 times--it is most likely a shorted convergence IC---the only way you can be sure is to remove the light box--I can tell you how by email--and unsolder the two STK-392-110 ic chips----they are on two heat sinks made of aluminum next to each other; if you open the back cover and find them you will see about a dozen blue(light blue) resistors marked 2.2 ohm----if any of those are some what white in the middle(discolored) they are gone and the set will never adjust until you replace them and the two convergence IC chips---What I usually do in this case is remove the light box and unsolder both IC chips and plug it in and turn it on---if the set now comes on and stays on--I replace the IC chips and adjust the set---I have done hundreds of these sets---3 blinks is almost always a bad convergence IC--if this was helpful give me a vote---AND IF YOU NEED DIRECT ASSISTANCE contact me at:

Turn on the power and the green LED blinks on the front for a second, but tv does not power on

MOST OF THESE SETS HAVE A SELF DIAGNOSTIC:


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

count the led blink as thats an error code. If it blinks three times its indicating the convergence Circuit has failed. Let me know the actual blink number and I will assist you.

Panasonic projuction screen tv.


3 blinks is the error code for the convergence ICs. You need to replace both STK392-110 convergence ICs. You can get replacement ICs at the following link and they provide installation instructions with pictures.

Power comes on then goes back off.


More than likely, the two convergence IC's have to be replaced.
