Question about Hitachi 50UX57B 50" Rear Projection Television
Great picture, but this last year it just started to turn itself off after anywhere from 1/2 hr to 2 hrs rare maximum! Seems like it overheats or something? help!
Resolder the horizontal driver transformer and all of the coils that start with "L77xx" on the left side of the sweep board, there is also a jumper staple just above L7711 that must be soldered it does not have a designation number but you`ll see the solder is bad on one end, very common issue with your model.
