I do not recall if the Norcent brand is still being sold actually. A plasma is really three components put together; electronics, glass and power supply. You have an electronics problem. Since plasmas at 42 inches are now under 1 grand, you have to weigh how much expense you want to put into this. As far sa a DYI approach, you could open the back and look at the boards and try and observe for a fried capacitor or something obvious. If you find it, youd then have to get that board and replace.
