may be the panel, in which case it should be under warranty. This unit has a 1 yr mfr warranty , if less than 1 yr old it would be covered. contact servicer for service immediately before warranty expires
Does it suddenly lose signal while you are playing the xbox? sounds like a loose connection on the input board in the tv. but it could be other things. does it lose signal on all inputs or just a couple?
It sounds like a shutdown circuit is being activated. This is normal in cases where the power supply id drawing excessive current. I would suggest that you get this looked at by a qualified professional. This is because this problem may be in the power supply and the voltages can get dangerous in this section of the TV set.
In any event if this is a power supply problem chances are the technician will just have to replace the power supply. Which should cost from 150-250 dollars.
I finally got information from the repair shop. Apparently it is the
upper and lower panel drive. The parts are supposedly not more than a
couple hundred dollars, though I'll let you know when I get the bill. I
do want to say that Hitachi was great when I called them. Even though
my plasma is out of warranty by a few months, they agreed to pay for
parts if I pay for labor. That just might keep me buying Hitachi
products despite the issues I've had with my 2 plasmas.
