Question about Hitachi 50UX57B 50" Rear Projection Television

1 Answer

Powering on Our 1991 Hitachi projection tv will only power on after clicking it on and off about 100 times. It almost seems like you have to warm it up to get it to finally turn on. What is wrong?

Re: powering on

Bad solder connections on main power supply board, you need to get it done, turning the set on that way will eventually cause the regulator circuit to fail, solder work is a cheap fix, call a tech and start enjoying your set again instead of fighting with it :), hope this helped, BMW Rider

I have a Hitachi Rear-projection TV that won't power on. What could be the problem?

This is probably a protective reaction from the set if it is repeatable and may be related to the power supply that converts your AC source into the necessary voltages the set requires.
Not a DIY repair unless you can find a used powers supply and want to try replacing it yourself which isn't a big job since these are connected by male/female connectors to the various circuits.

No guarantee that replacing the supply will make the set usable again.

It may be time to shop for an LCD TV to replace your projection set since repairs and parts will be getting tougher to find.

If you find one you like, enter the make and model here at Fixya to see if the brand or model is causing problems for owners,

Hitachi 60sx12b. when you turn on, clicking sound, don't turn on.

Replace micro fuse F903 (5amp). It's located near the biggest 2 caps. in power supply area.

Powering on Hitachi TV

If all you hear is a click and you get no display on the screen, it sounds as though you need a repairman to come out and fix the circuit board. There are several things that cause this symptom on your set but the most common are convergenge amp failure, vertical, or power supply issues. Sometimes as simple as resoldering connections. Other times major troubleshooting and part replacement are required. The repair cost is usually between 175.00 and 375.00 hope you have a trustworthy and knowledgable repair person, good luck, Russmann.
