Hi,

The 3 blinking lights on your model can mean several different things, I have seen it cause at least 3 that I know of...

The first and most common is the convergence circuit, to repair this you will need to replace both convergence output IC's, normally you can determine that this is the problem by turning the set on while watching in the back, a lot of times there is a resistor in the convergence circuit that will glow bright orange.

If it is not the convergence then I have seen a problem in the vertical and horizontal circuits this will require troubleshooting though to know what is going on, most likely this will require the replacement of the vertical output IC or a cap in the horizontal circuit. I do apologize that it wasn't as easy as you were hoping, unfortunately that 3 blink can mean many different things, basically the set is going into shut down but what circuit is causing it will need to be troubleshot to know for sure.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

    You need to troubleshoot vertical and horizontal circuits. Do you have the schematics for this Model?

    Let me know,so that we could proceed.

    Hope i helped you.

  • miketv10 Jul 18, 2010

    I do not have the schematics for this television.

  • miketv10 Jul 18, 2010

    Could I just replace the cap and output ic? Or would this not be cost effective? I already purchased new convergence ic's.

    Thanks for your response!!

    Most of the times, i have found Vertical output IC or a cap in the horizontal circuit to be at fault. You could try to replace these and see, if that would work.If not, revert and i would be glad to assist you.

    Let me know,if needed further assistance.

    Hope i helped you.

Pt-53wx53 Panasonic Projection TV Turns off


OK< likely one of the new chips are bad or when soldered in you shorted pins at that time----3 blinks is short protection and you are going to find ONE of the light blue 2.2 ohm resistors is open (usually discolored in middle).

Having changed hundreds of chips in this model once in a while you get a new one that is bad---replace both again.

How did you get at them----remove the board or pull the light box?

PT-53WX56


yes the 3 blink error code means the convergence ics need replacment. very easy you need two stk392-110 ICs and six 2.2 ohm 2watt resistors very easy an inexspensive repair. you can get replacement ICs and resistors at the following link with free instalation instructions with pictures so you can do the repair yourself and save quite a bit as a repair shop usually charges between 4 and 600 dollars for the repair which takes about an hour. Heres the link.
