Lg 150 cm rear projection

I'm having problems with my lg rear projection, blue color started to come out on the bottom sides of the tv, the more we use it the color blue spreads. It's already covering 80% of the screen. It's still watchable but it's not as clear as before most of the color of the tv is gone, I got an electrician to have a look at it, he said i have to change the whole engine, not quite sure what he meant by that. I was told by him that the parts is no longer available to purchase.

Hello, I have an LG lcd rear projection tv and parts of the screen are turning blue, do you think it's just the bulb or the light engine?

Hey there first of all your tv is a lcd rear projection set, this tv's don't have a light engine system, they use a optical block

whats happpening is that one of your lcd chips is burning out and this problem will start to get worst, to be honest with you it's very hard to purchase just the LCD chips, you need to buy the optical block to fix your set, also the bulb has nothing to do with the color the bulb just shoots out light.

please rate this solution!!!!!
