TV had quit turning on about 6 months ago. finally read an article online regarding two capacitors going bad in the power supply board. found them easily, removed them, replaced with 1000uf 50V. TV now turns on! (saved a lot of $$ *yay*) but now the picture is grainy, almost like old VHF tv. 1080 looks more like the year 1980 tv. Computer graphics on PS3 games look GREAT! but blu ray is real grainy.
