    You say there is an I.C. with its top blown off?

    That is good as it really helps diagnosing which borad is the problem.

    Bad news is you should plan on replacing that whole board.

The blinking light tells you what is wrong with the circuit. If it blinks 3 times it is the convergence amplifiler. I had this problem and tried to fix it myself and I don't think that I have it connected good enough. I know this is the problem with mine. I will let you know if this fixes that. Let me see what 5 blinking lites mean. I will tell you what each blink means from the repair manual, 1 blink is +140 circuit, 2 blinks is Low DC, 3 blinks is convergence, 4 blinks is HHS, 5 blinks is IC4011, 6 blinks is IC4018. I hope this helps. You can get a repair manual at servicemanuals.com it really help

    the solution was posted from fixya itself.
    tell me if it works.

  • dewan nafees ahmed Jan 01, 2008

    its not a common problem and all.
    6 blinks is IC4018 damage.
    this indicates that that IC has to be replaced.
    if you are having good knowledge in practical electronics you can open the set and chage for yourself.
    else its not advisable. so better call a tachnician and he will fix it for you.
    thanks brother.

  • dewan nafees ahmed Jan 01, 2008

    thanks for replying brother.
    problems do come with TV sets. you both have bought at the same time right.
    so there are chance that that batch of TVs produced may have been used defective ICs.
    and one more thing to be noted.
    if you have been satisfied with this solution you need to change the rating of mine to fixya. for that try to change my solution to fixya else if not send mail to fixya about this issue.
    anyways thank you brother.

    or try removing and re-installing the lamp cover on the back.
    may be the lamp cover
    is not seated properly causing the safety switch to not engage all the
    way, when the lamp cover heats up and expands, it fall away further
    from the switch tripping it, shutting the set down.
    when you remove
    and re-install the lamp cover, after you take the single screw out,
    tilt the cover out and forward from the top about 3/4 of the way out
    and then tilt it back into normal position and put the screw back.

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.

Panasonic TH50PH10 Turn off Automatically


Hi, if your plasma flashes 10 times it means that there is a problem with the sustain driver. This could be an intermittent problem, such as when the set heats up. It should be returned to the dealer as it is under warranty.
