    I have a Hitachi 43uwx10b rear CRT projection TV.


    • First problem was that the TV would turn on but no picture. It had a blown protector fuse FP05. Replaced the horizontal output transistor Q777, snubber diode, a couple of metal film caps, etc on the deflection pcb.

    • The TV does now turn on, I can see the menu come up on the scrren but turns itself off after about 5 seconds. I tried this about 4-5 times and still the same symptoms.

    Any ideas on where to go next. The service manual is less than helpful for troubleshooting.

Can you post the model number please. Also, are there any other symptoms at all? Do you hear sound? Can you hear the high voltage kick in before it shuts down?
Thanks,
Dan

For about 4 weeks in have been getting a notice when I turn the tv on about a lamp timer needed to be reset. While the TV was on it cut off by itself. This is a panasonic 43" rear projection LCD TV. It is...


While TV is on, simultaneously press and hold both the TV's Volume Down button and the remote's PP/Play button for 7 seconds.
This is the procedure for resetting the lamp timer. Have you ever replaced the lamp before? The lamps usually never last 5yrs.

Panasonic Flat Screen TV turns off by itself


If your unit was blowing fuses you must have had an overload somewhere. Your post is not clear. Does your unit run ten minutes after unplugging and replugging it? If it does then there is still a partial short in it somewhere which causes it to shut down for protection. It could be anywhere. Some detail on what happened prior to the fuse blowing would be helpful for diagnosis. You do not sound like you would have the expertise to troubleshoot this unit. I doubt there could be much wrong with it and the cost should be minimal. Find a reputable repair shop to handle the repair. Good luck.
