It's the light polarizer on the blue lcd panel. it's fried due to excessive dust and heat. unfortunately you'll have to replace the optical engine.

I have 2 epson EX31 projectors in our sanctuary that run the same image from the MAC. (song lyrics, slides, etc) Recently I replaced a bulb in one...and since then...the "White" levels in the projecto

If uniformity of the images is important, I would reccommend replacing the second bulb on the other projector with the same bulb, from the same vendor as you did the first. It may be too difficult to match them up otherwise (assuming the first bulb you bought isn't defective).

I hope this helps,

How do I change the lamp? Lamp came with no directions. This is a HD72.

Hello there,If your movie projector light bulb has stopped working, there are some simple steps to take to get your movies playing again. The hardest part may be finding the correct replacement bulb. There are so many different models with their own specific bulb. Here are some steps to follow to replace your burned out light bulb.
  • Locate the bulb in the movie projector. You may need to use a screwdriver to open the bulb compartment. Check your owner's manual for proper procedures.
  • Step 2.Remove the movie projector light bulb or lamp. The bulb must be cool before you take it out. Use a tissue or cloth to remove the bulb because the glass bulb is very fragile. Do not throw away your bulb yet, you may need it to help find a replacement.
  • Step 3.Find replacement bulb. The Better Lamps website offers a wide variety of light bulb models. From their homepage select the brand of movie projector you have and using the model number from your old bulb, buy a replacement.
  • Step 4Replace the movie projector lamp or light bulb. Do not touch the bulb with your skin. This can transfer oils from you onto the bulb resulting in a hot spot which can make the bulb burst. Use a tissue or cloth to handle the new bulb to screw it back into place and then replace the cover.

    I have a panasonic pt l500u, just started getting large yellow spot in middle of screen- looks like a giant finger print. Bulb was replaced less than two months ago.


    The problem here is the one of the miniature LCD screens in the unit is faulty, in this case its the blue one. There are three of them inside the unit RED<GRN<BLUE. The blue seems to be failing in your unit, for instance if you mix red and green you get yellow. Have a local shop service the unit and clean and refocus the unit back to factory spec's..

    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.

    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

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