Question about Hitachi 50V500 50 in. HD-Ready LCD Television

1 Answer

Blue shadow I just replaced the bulb on a 52 inch zenith lcd tv, model number M52W56lcd. After replacing the lamp, I was presented with a blue shadow about 3 inches thick running half the length of screen on the right side. When removing the lcd screen, I see the blue shadow present on the projection mirror in the back of the tv, before it is reflected to the actual screen for picture production. Is this an issue with the new lamp?

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.

Zenith M52W56LCD picture is turning green.


The light engine on your set is burned out.
This is a very complex replacement.
I hope your tv is under warranty repair cause it is expensive.
It happens because the heat from he lamp over time burns out the lcd's that create th ed and blue leaving the gren which is always furthest from the lightbulb (YOUR tv has four lcd's in a row..red, blue, gren and then black.
If you wish to try and replace it yourself there are places online where you can buy a replacement engine.

Zenith M52W56LCD blue spot in center of screen


It could be as simple as dust contamination in the LE or lcd chip. You need a clean room to work on this area of the unit and NOTHING you can do there would make that possible, short of spending a few thousand to build one. Before we added a clean room enviroment we simply pulled the LE and sent it in to PTS - who has one and reinstalled...
In your case take it to a qualified shop and you'll save yourself a lot of grief..
