It isn't the LCD panels, it is the Polarizers that degrade with heat. You can replace them yourself.

Your projector lcd panels are dying. This problem is as old as the lcd projectors themselves. Not a field repair. They are installed and aligned and glued in a clean room enviorment. Consider purchase of a dlp projector, much more reliable

My projector shows a blue tint to the right of the screen. I am afraid that it might be the blue LCD panel gone bad. What might the diagnosis be? Sony VPL-HS51


Does the blue tint show up as small rectangular pixel shapes when you get up close to the screen when focused properly. This would indicate a blue LCD panel fault. If it's fuzzy then possibly a blue polarizer overheating

I have an old Sharp XG-E1200 LCD projector that has a flashing blue tint over an otherwise nice picture. Any idea what that may be? I want to get some idea what a repair might cost before paying a...


That is generally caused by an LCD imager being either faulty or the bias may be incorrect. I expect the repair man will say the Blue Imager is Faulty and he will possibly be correct. It may be an adjustment but not very likely,
A new imager will cost an awfull lot of money.
Hope that helps.

Projection has yellow tint


From your description, it sounds like a problem with the blue color. Green LCD=purple onscreen, Red=cyan(baby blue) onscreen, Blue LCD=yellow onscreen. It could be a lot of dust on the blue lcd panel, or worse, might be a burned polarizer filter behind the lcd panel due to excessive heat. If you can focus on the yellow and its tons of yellow specs, its dust. A burned filter however, must be replaced. A technician trained in projectors will have to do it. The filter material is glued to a thin glass panel and is replaced as a single filter. It's a very involved repair.

Images has a blue color across the center


Wow, 3 in a row. As described on 2 other projector issues this is very similar to those others. I'll repeat the info here.

I assume this is an LCD. I don't remember the s4 being a DLP projector.

This sounds like the LCD panel used for the blue color has gone out. The image is made up of red, green and blue images layered upon the screen. If the blue panel has gone out then there is nothing filtering out the red light in the image.

It looks like yours has just a secone of the panel dying or comming loose from it's connector.

It could be a simple open and reconnect fix. I personally have never opened a projector, so I'm not going to walk you through it as I do not know how hard it would be to tinker with. It should eb a cheap fix for a true repair man though.

Image has big yellow


Hi Zenmast

This is a burnt LCD that will need replacement. If the circle is yellow on a white screen , then it is your blue LCD that will need replacement.

I had the exact same problem with my z3, Turnes out it was the blue filter.
I used the full service manual, and managed to fix mine using the diagrams, and troubleshooting section.

Bright yellow


I can't imagine a setting that would cause this - It sound more like some sort of fault with the projector's blue LCD panel. (The image is created from a mix of red, green and blue light. If you loose the blue, everything will look yellow.)

Is it capable of showing any shades of blue?

Using any graphics or photo-editing software, create a solid blue image (R=0, G=0, B=255 in your colour settings) and if possible, display this full-screen. Is there any output from the projector at all when you do?

If not, it sounds like it need a professional repair.
