Probably your blue CRT, you can look down in it after taking back off and see if it's the fluid is contaminated. If so it will need changing. This should be done by someone who is qualified, because you can damage tv set.

    CRT is the tubes inside set. If you are looking from top of CRT down inside there is a fluid that covers all 3 tubes, this sometimes gets cloudy usually starting with the blue tube. Check it against the other two.

The colors look very weak. The green is weaker than the blue. Red seems ok. I have a philips 60 inch rear projection. It almost looks like a haze. The colors are not crisp. .


The TV has coolant in the CRTs that after years of use get cloudy. you will need to have a shop replace the coolant in all three, it is pretty involved so its best to have a trained tech. do it.

LG LCD REAR PROJECTION BLUE HAZE -RT52SZ30RB


Have heard that it's a common problem, there's an issue with the optical block. Sony is susposed to be aware of the problem & has exptended the warranties on some models or offers gift cards towards the purchase of a new tv, depending on how hard u push once u get someone on the phone.

Green dot in middile of my screen


The green dot in the center sounds like a burn mark on one or more of the picture tubes inside the set, and the curved lines are telling me that you have a problem in the convergence circuits. The blue haze around everything white tells me you either have a lot of dust build up on the lens over the CRTs, or your picture tube(s) are very weak. If this set is over about 12 years old, I would replace it. I doubt if you will be able to get the green dot out of the picture without changing the tubes which would be VERY expensive.
