Yellow spots on screen - Sharp Notevision PG-C45X Multimedia Projector

one of the three polarizers is burned up It can be repaired

The set if projection which model here is, has arced and now each of the three picture tubes used has a tiny permanent burn mark on its screen.

That is what you are seeing, the set uses three picture tubes with screens like the old tv sets===the coating has been burnt in each, want to prove it, remove rear cover and cover any one of the three lens and that mark on one tube will go a way.

Not fixable.

Yellow spot is mainly due to lense stain , so clean your lense from inside. it will solve your problem.

I think it helps. let me know.

Hi , it seems you are experimenting a light engine problem.Here's how your tv works: http://www.youtube.com/watch?v=ZLLHnQ4y-wo Basically there's 3 LCD chips that create the colors and image by blending together.When these chips start to melt you will get those blue spots, pixilation even vertical lines.You will need to replace the light engine. Have a blessed one!

the lcd panel for the blue is bad normally you would have to replace the engine but i know a place where you can get it rebuilted for a price cheaper than the engine go to
N-home tvservice.com for some answers

Hello,
Unfortunately the discoloration is caused by the extreme heat generated by the Lamp has burned the LCD optical polarization filter/elements.
The only solution for this is to replace the entire LCD optical assembly.

Sorry for the bad news, :(

I have a similar issue with yellow pattern on the left and top right of my screen. Took it apart and found the blue lcd had damage that matched the yellow area that was projected. I thought it was the lens but it was the blue lcd .It has gone bad and no replacement. Are you interested in selling the bulb or the whole projector? I have since purchased another projector and am keeping the bad one for spare parts. Hope this helps..Ben

This is probably the polarizing filter. It will need to be replaced. It should not cost very much to fix.

Hi hope you fine.
is it just a spot or a continous line kind of?
is just a spot check the service kit on the front door (ETB ) alighnment might be touching the prnt drum units.

I have no suggestions but I am having the exact problem, yellow haze in the top right corner of the screen with a yellow line running down to the bottom of the screen. I guess we need to call tech support.
