Solved!My Toshiba 49L621U goes dim, then bright, then dim... Can't seem to adjust anything to correct this. Anyone have any issues like this that could help?
is it like a disco light? if you have experience about diassembly and assembly electronics ... try to clean the boards or go to repair shop .. it must be a tiny little shorted circuit on light panel.. if its new then could be software bug
