    Oh sorry I'm new to this blog I thought it would post under the problem about the Hitachi 50GX10B that keeps shutting itself off. I finally found my TV guy and he thinks its the "convergence" thing. It sets on the right hand side of the set (if you are looking at the back of it) and its a silver box with a board attached to it. He's really awsome and is charging me $200.00 to have it replaced. So you think that was a fair price? The picture on this Hitachi is still very very good so I would actually hate to go out and purchase an 50' LCD. But this part has went out before - is this a common problem with that model? I purchased it about 2001 for $850 - new from I think Circuit City.

I dont have a clue what your symptoms were, you have to keep responding to the origional post or I have no way to determine any previously posted items for your problem.

    Yes 200.00 is a fair price to replace the convergence ICs. It could verywell be that if your picture is out of alignment as a bad set of ICs will distort the picture and will cause the set to shut down. If the picture isnt out of alignment, then It wont be the convergence ICs that are shutting the set down. If you need more assistance please let me know.

The TV just shut off on its own. Why did it act this way?

The TV will shut off when it's drawing more power than it can handle. It will also turn off if a sleep timer is set in the settings menu, or if it's overheating. If you have a lot of devices hooked up to the TV, I would suggest turning off or unplugging anything which isn't in use. Also if your TV doesn't have room to breathe, or if it's not well ventilated, certain components may be overheating, which may also cause it to turn off.

House breaker triped I reset it but now my Hatachi 57TWX2OB has no picture or sound but power light comes on on front panel

hi, you might get lucky and have a locked up micro, un-plug the ac cord for 1 minute and then plug back in, this will do a hard, set-re-set of your tv. If still dead then power supply has been damaged and you`ll need a tv tech to diagnose it, good luck, video-tek

This can be a number for things. Believe it or not dust or cig smoke in LCD and pix tube projected TVs turns up looking a lot like focus error. Is the focus bad or do you have a convergence error (red, blue or green shading) Is there any smearing or blooming to the pix? The other comment for you is the TV is 9 years old I personally consider this very close to the life of the product. A simple good pix would tell volumns for someone like me (may need some resolution on the pix).
