Hitachi 50SBX78B 50" Rear Projection TV

My power supply has blown. Darkened capacitors, darkened area on circuit board. TV had a beautiful picture until then. I refuse to throw it away and buy a new large screen tv. Does anybody know of a source for this power supply board?

    Were watching tv and suddenly the picture and sound both went out. Had a bad burning smell. Tried unplugging and plugging in again. The power light starts coming on and then quickly goes out. No picture or sound still. Help!

If the power supply board is the only thing affected, I would suggest calling PTS:1-800-844-7871 and give them the model and what you are looking for. This would be the simpliest thing to do. They rebuild boards and maybe more cost affective than trying to repair yourself. Hope this helps!

Hitachi LCD M50VS810 -- picture gradually darkened up over the past 4 days and now picture won't come on. Replace bulb?


If it uses a lamp that is possible---sets with a lamp will often dim down just before the lamp fails in a total way.

Nothing on my TV


This set has CRT guns. 3 of them. No bulb.
Check and see on this site what others have suggested for your problem.

Without seeing it I'd say main AC fuse

Hitachi model #60SBX78B


The green led or lights on the board indicate some of the power supplies are working. The key is do you see any come on and then go out. this would indicate which part of the power supply is failing. also there are fuses in the set that do not look like your standard glass fuse. WARNING television generate lethal voltages that will hurt you. extreme care should be used.
