Question about Philips Magnavox 51MP392H Rear Projection Television
You may have a short between the grid and the cathode of one of your tubes. This is repairable if you happen to have a CRT tester. It can remove the short and allow you to balance the three tubes once you have repaired the problem. There is information on the web about how you can clear the grid / cathode short by using a charged capacitor across the grid and cathode pins of the CRT.
I would suggest, though, that you get a qualified TV repair person to do the work on this TV. Since the voltages involved are rather dangerous.
I hope this helps,
