Mitsubishi wd-60c10 about 2 yrs old, on 3rd lamp. First one popped after 1 1/2yrs. Second one dimmed after 3 months. Have new one installed and now other problems not sure if its from lamp or other issues. Mitsubishi wd-60c10changed out 2 lamps past 3 months, now the tv has a scratching sound and the picture is snowy when on cable. When I change it to hdmi 1 (ps3 hookup) picture is miss colored and flashing looks like a strobe light. I pulled it apart cleaned it very good fans for sure. Put it all back and the scratching sound quieted a bit. The picture is still the same. The tv shuts down automatically after several minutes. Does anyone have a clue? Hoping its something I can take care of myself. Please help thanks
