I have a hitachi LCD rear proj tv, model 50vs69a. The picture is very dark ESP when watching a movie at night. I've tried all adjustments suggested in users manual with no success. Help!

toni, you`ll need a tv tech for this problem, spark gaps need to be cleaned, crt sockets need to be cleaned and crt pins on all 3 crt`s need to be sanded, this is a common issue with this model set, good luck, BMW Rider

Replace both convergence ICs nuber STK392-040 that should take care of the problem. you can get new replacement ICs at the following link and they will send free instalation instructions with pictures so you can install the new ICs. heres the link.

I FINALLY got the problem fixed!!! Gee I feel stupid. I called a great local TV repair guy and he came out and fixed it for next to nothing. The stupid part is that all he had to do was take apart the TV's front fascia and clean the mirrors and things inside....it was FILTHY!!! Then the TV was like new again. It looks so good I wanted to kiss him. He advised that you really should be cleaning that about once a year or so to prevent this problem. Also, I live in Nevada with HIGH dust so that doesn't help either.

To do this, press the ENTER button on the TV and the MUTE button on the remote at the same time. After 5 seconds the screen should come up and it will read "Lamp use time...Total lamp use time ....lamp reset" Press the center button on your remote (the circle button right in the middle of the four directional buttons) and you will be reset to -0- again. Your orange light should now be off.

Do you have a center speaker near it? maybe move it, that is what I have done and it seems to have gotten better.
