    I have a LG 50pc3d plasma tv that is doing wierd thing when you power up after tv has been off over night or long periods of time.When you power the tv up it cycle on &off for about 15 mins. then stay on .It has a mind of its own .i can't cut off with power switch during this cycle .Ive got to cut breaker off in fuse box since the tv power outlet is on wall an can't reach it.Do I replace the power board or the caps.Seems that power boards are out of stock for this model. THE TV IS FREAKING ME OUT HELP!!!!

    Re: Jw60

    So after this 15 min cycle it will work normally i.e. cut on and off without any probs?
    Is it about 15 min everytime?

    So we can safely assume it is within the main or the power supply. But to be sure I would unplug the Z and Y sustain boards to make sure it's not faulting the power supply (though very unlikely since it is restarting)

    Open the tv and check for bad caps (bulging) especially in the top left.

    Do you see about 5 3300 uf 10v caps?

    And future reference, it might be wiser to include the model of the the tv and slight descrip of error in the title so those who have experience with these sets can help you (or at least quicker)

    Oh and if you can, please include pics.
