Question about Projection Televisions

1 Answer

Hitachi 50 Inch rear projection TV, Model 50UX58B. TV made a popping noise and then shut off. I unplugged the set and waited about a minute to plug back in. Pressed the power button. The red power light comes on momentarily and then goes out.

    Thanks for the help. After thinking about how much I wanted to invest in a 10 year old TV I opted for sending this one to the graveyard. I think it is time for a new HDTV bigscreen.

    I have the same problem is there a fix? It seems like a power distribution problem, by taking the back cover off and pressing gently on the motherboard near the power distribution it comes on...

That could be many different things such as a defective CRT, A capacitor that has shorted. or the flyback. Unless your good at electronic repairs it may be best to call in a repair tech for that type of issue as I have only just lightly touched on the possible causes.. It will need to have the standby and operating voltages tested to pinpoint the problem if it isnt noticeable by visually inspecting for blown components such as capacitors

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.
