I have a 50 inch Mitsubishi plasma monitor model# pdp5010. This set will work sometime for 30 min are so then goes dark with just the pixels flashing on the screen. Sometimes after awhile it will come back on with a normal picture. Has anyone had this type of problem on plasma tv?
This really sounds like the sustain power supply has a problem. This is not the type of repair a novice should try or even lets or attempt to repair themselves. This is just too of an expensive YV set to try or experiment with. Good luck with the repair of this TV set, and please keep us informed of the repair of this set.
