    The set was off during a lightening storm. Would not turn on afterward. Replaced fuse , no help. I read that the problem may be the power board but I don't want to spend $50-$60 and then have it not work. Prior to complete failure the back-light came and went, pic was bright then dimmer. I think the 2 things are related. Does anyone have thoughts or experience with this set/problem.

    Thanks in advance.

    Hi Rick,

    well i had a similar issue on a big Toshiba LCD TV. Lightnings can destroy several things (tracks, diodes, transistors, resistors ..), and can also change resistor values. It took me more or less a month of nights spent on it, but was a challenge and a learning experience. At the end i replaced several components and reconstructed some tracks here and there and got it working.
    This doesn't mean the same happened to you, but, the repair could not be that simple.

    If you want to try, let us know, i can help you on how to proceed.

    Ciao
    Angelo
