I am having the exact same problem with my Toshiba 42HP95. From the information that I have been able to glean from the internet, it looks to be some sort of problem with the power supply or some other component of the power circuit. I am giving up and getting service

I had the same problem. It turned out that one of the cooling fans get dusty and does not work. I opened the back of the Toshiba plasma TV and cleaned the failed fan, and it worked like a champ.

I think that the pop you heard was an electrolytic capacitor blowing its top on the picture frame board. If you are able to check this for yourself by looking on the board for the one/s with a bulging top or are a brownish/black colour like something has caught fire. And also in this situation smell can be of great help as it will smell burnt out but PLEASE before putting your nose or anything else in the tv take all necessary precautions against electric shock and discharge any electrolytic capacitors in the vicinity. If you are not able to do this yourself find a competant technician. Hope this helps.

this sounds like a dmd board problem. these are digital modules attached to the light engines usually. samsung, rca, hitachi, have shown similiar symptoms. some units have capacitors on the boards that can be replaced, but these are dual-layer pcb's that are tough to unsolder without proper soldering iron temperature and good small gauge solder-wick. or solder pump tool. the electolytic caps. are usually 1000uf / 10v, 330uf / 10v, or 470uf / 10v. alot of the time the capacitors will "vent" or swell-up on top which helps spot faulty component. we always increase voltage rating to 16v-25v for more reliable operation. always use 105 degrees high- temperature replacement caps.
