    If you got 7 trouble-free years from your flat screen, you've done well.    The power board for most plasmas is ~ $150 ... but this varies quite a bit.    If you post the model # of your TV we can probably find it for you.

    As for determining whether it's the power board or the fan ... difficult to say.    If the fan's not spinning it could be because it's defective -- OR that it's not getting power.    I suspect that's why the lights aren't definitive.    Unless you have the appropriate meters (a simple multimeter is fine) and knowledge (so you know what to measure to confirm whether the PB is good), it's likely easier to just replace them both.   Especially if you're going to have a service technician work on it, as the labor charge is likely more than the parts, but will be about the same whether or not he replaces the PB, the fan, or boht.

    Note also that prices have dropped a LOT in 7 years => this may be a good time to consider an upgrade to a newer/larger/more-fully-featured TV.

    its was given to me to see if I can fix it and the only tv repair is in seattle about 1500 miles away I kind know its a long shot to try to fix it but I just can see dumping it in the trash.

    I'd disassemble it and remove the power board, then Google the PB model # and see what it costs on e-bay.     As I noted above, these can vary quite a bit, but are usually in the $100-$150 range.    If you're willing to risk that, you can likely have a nice TV for a very modest price.

    But as I noted above, TV's have come a long way in the past 7 years ... be sure to check what a new model in the same size would cost you before deciding if you want to spend the $$

    ... if you truly "... don't want to spend money on it ..." you're likely out of luck.     One thing you could check is the capacitors on the power board -- this is a very common failure mode.    If they're bulging/leaking, it's likely the failure is simply due to bad capacitors.    If that's the case ... and if you're handy with a soldering iron ... you may be able to repair the board for $10-$20 worth of capacitors.
