Question about Hitachi 50UX58B 50" Rear Projection Television

1 Answer

Hitachi 50UX58B won't turn on

When the above TV is plugged into the STB from a switched outlet and the STB is turned on, the red light on the front of the TV comes on, but then goes off slowly (a few seconds) like a capacitor is discharging. When the TV is plugged into the wall outlet, I can't even get the red light to come on at all either manually or with the remote. Its like the TV is dead. Any clues where to start? Where can I find schematics? Thanks in advance

Hitachi projection TV does not power up


You probably have a blown 2kV capacitor and 2 amp fuse. Look for signs of black burning inside.

Wont power up


I have seen that symptom many times. Most likely, the little blue capacitor next to the horizontal output transistor has shorted and popped the main B+ fuse. This is very common in those Hitachi projection sets. These parts should be replaced by a tech familiar with Hitachi projection sets.
