    i was having a convergence problem. i changed both stk-392-110 to stk 392-180. i adjusted the convergence and got a perfect picture. i left the tv on for twenty minutes to check befor putting all the screws back in and closing the back up. i turned of the tv and attached my media devices. when i turned the tv back on i got three blinks and the tv shut off.. does this mean my new ics are shot, resistor shot or is my soldering bridged somewhere

    Hi,

    I have the same no power/ 3 blinks issue with my Panny PT53Tw53. I opened her up and disconnected all the wire harnesses in prep for swapping out the 2 convergence amp ICs.


    Question: how do I disconnect the red high power lines from the power supply to get the board tray out to do my soldering??? Or do I perform the work will the tray is vertical?

    Thanks,
    Jerry


    P.S. Please help. I love this TV and to see it dead saddens me :(

I would say to replace the stk 392-110 ic with a set of stk 392-180 the 180 will handle up to 18 watts instead of 11 watts plus they seem to be more thermal protected, DONT FORGET TO PUT A NICE COATING OF HEAT SINK COMPOUND ON THEM

First of all thank you for the compliment. 3 blinks on the led means shutdown due to the convergence circuits. Its an easy repair you need to replace both convergence amp ICs thier numbers are STK392-110 I will post a link where you can order replacements and they provide free installation instructions as well as free on line tech support while you do your repair by way of instant messaging. I am one of thier repair techs that does the online support. just go to this link i am posting and purchase two STK392-110 Convergence ICs they ship free anywhere in the world. If you need other items such as solder irons and what not just leave a request by clicking the contact link in the lower left collum as they sell all those items they just dont list them all, and they will respond fast telling you what they have.

NO, three blinks on most of the sets means short protection.

If model is similar to one listed here it means short in convergence circuit. What happens is one of the two convergence output chips goes bad and takes out a resistor or two around it; set senses no voltage to chips and shuts down with 3 blink error code.

This can be a do it your self repair if you are handy and soldering is involved, typical parts cost at a site I use is well under 25 dollars.

Time to get a new TV. I have similar problem. In my case, the set turns off, LED blinking green for about a minute or 2, then the set will turn on by itself. Something the LED started to blink yellow after blinking green and then shuts off. I can turn it back on. This happens 3 or 4 times in an hour. After that, the TV stays on for as many hours as I want until I shut it off.
And then the problem repeats everytime I turn it on from a cold start.
I have my eyes on the 50 inch Plasma from Panasonic. Bestbuy has one for 999.99.
