You need to reset the lamp counter if it reaches 16,000 hours. The tv will not turn on once this limit is reached. With the tv remote, and the tv off, push the ? Button on the remote, then 9876, then push the enter button. The three lights on the front panel will flash indicating the counter has reset.
No. I would suspect it being a Optical Block issue. I is not a pretty repair not to mention the cost factor. If you could get in touch with Hitachi Customer Service they could lead you to s service facility that could comfirm what I think.
your tv is talking to you basically, is telling you that the lamp has to be replaced. this is a common problem with this dlp tvs, when the lamp is bad the shuts off within minutes, so just replace the lamp my friend.
Long story short: The blue fog problse is the light engine. Specificaly, the filter for the blue LCD gets to hot and over time starts to burn up and disinigrate. (I just tore my set apart thinking maybe it was the blue panel and found this was indeed the culprit for this problem).
As far as a solution? You will either need to replace the light engine (expensive) or replace the light filter which means tearing the thing completely apart. then there is the problem of where to get a replacement filter. Does ANYONE know where?
As far as the lamp goes, might be time to replace it. You might be better off just getting rid of that TV and get a new one.
Chances are, if it's an older set, componants have changed value through use over time, which also includes the picture tubes and associated driver circuits. The way to compensate for this color drift is through adjustments. Either turn the red down a little, or turn the blue and/or green UP. Be carefull though as there are potentially dangerous voltages in and around the circuit boards and picture tubes.
