Hey John

I seen you posted in my thread.

was wonder if this has a blue board?

If so this is a inverter board I think

disconnect the ccfl which are on the inverter board.

then try to turn tv on, see if it stays on.
If it does stay on it could be the ccfl bulbs.

If a CCFL is disconnected, it should shut down within a few seconds... do you mean disconnect the inverter?
