Light Blue Haze close to the center of the screen


The Optical Engine needs to be replaced. You would need to contact LG / Zenith to get a Service Facility out to confirm the problem and see if they would be willing to help you with the cost. If they do not help with the cost, it will probably not be worth investing the money into it.
I hope this helps,

Yellow circle


The huge yellow circle is either your blue filter is burnt out (very common in Zenith DLP) or you LCD cube is bad. I would bet it is the blue filter. Zeniths DLPs have 3 color filters one blue (a pinkish color), one green (a grayish brown)and one red (it is red). For the bulb indicator I would check and make sure your lamp is seated to the ballast correctly. Just take it out and put it back in.

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..

Blue cloud on screen


Optics block or "light engine".. lots of $$. LCD filters have warped due to clogging of intake air filter resulting in overheating. The area in question is nicknamed "the cube" and is actually NLA for some brands.
