One of the light filters on one of the lcd panels is fried due to excessive dust and heat. clean it out with canned air. unfortunately, you'll have to replace the entire optical engine. sorry.

I have a ultravision 50v500 and it has a blue blob in the middle of screen. I have just changed the bulb with hardly any change in the blob. I also had the light engine changed approx 2 years ago.


That is caused by excess heat possibly due to poor air circulation/blocked filters.
It is damage to the LCD panels. It won't get any better, just worse.
So look for another Blue LCD panel and someone who is experienced to fit it.

Sharp notevision xgnv6xu oval yellow spot


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

Yellow middle, Blue Exterior


Hi Druaga

This is a Blue LCD Polarizer that will have to be replaced if the spot shows yellow.

You will find that this will only get worse as time goes by.
