I made the mistake of plugging my philips plasma into a bad outlet. I heard a pop come from the outlet and saw a little spark, followed by a very small puff of smoke. The tv turns on just like normal. If a put it on tv mode (coax. antenna innput) it works fine, hd picture and all. The problem is when I try to use my hdmi inputs, I get nothing. No flicker... nothing. The menu screen for the tv comes on etc., but no picture. It makes me think I have an issue with a fuse. Are there fuses on plasmas on each section of inputs. Anyone dealt with a fuse on a plasma? Like i said its a philips plasma 50PF9830A37, but the internals are all Samsung from what i remember.
