Hitachi 46UX50B high voltage transformer issue

I was just told my HItachi 46UX50B needs a new high voltage transformer, but they want $500 to fix it. The tv is 10 years old...but I found a replacement part for it for $100. Anyone know how difficult it is to change that out? I'm very handy with everything, but never messed with tv's before. Thanks for any assistance!

    I have a similar problem. When power button is pushed it shuts down immediately. Before turning on the power button . Inside the red led is lit with several green leds are lit. As soon as the power button is depressed all leds go out. Unplug and plug back in, all leds lite up. Though some do not seem to have the brightness as others. As soon as powe r button is depressed all go out. I need some direction in trouble shooting this problem.



    Thanks

    Mike

Hitachi Ultravision 46UX50B Flickering/Dead Display


It is possible that you have some loose connections, but I have seen the relays in the power supply get to be intermitent and will not stay closed. Tapping lightly on the relays will usually tell whether or not they are bad.

Hitachi 50UX11K picture is scrambled


jansen6pack- I am currently repairing the same tv, what I found is that the video pak is going.I have checked pricing and the unit is about 500 bucks,but if you take it to a repair shop they may be able to repair it or send it away for repair. It may be worth the estimate charge. cooltekFeb.18/08

Hitachi


TV's have a circuit that monitors the high voltage and shuts down the power if it senses something amiss.
On projection types, figure on just replacing the entire board that has the flyback transformer on it.
Hope ya fix it!

The steps that need to be taken on fixing this set start with the standby voltage requirement. Is it there? next is the low voltage loop from the transformer, also a requirement for the set to come on. ...accordianman

Flashing Screen when earmed up ?


Set should take 90seconds to "warm up" maximum. Check high voltage circuit and flyback output voltage. Bad transformer or the regulator should be suspect.

Hitachi model cu4601b/k


I had this problem in a 46UX50B (I think that's the model), and it turned out to be some capacitors in the power circuit(?). After the service guy replaced those, it hasn't failed to come on since.
