Question about Epson Pro Cinema 7500ub Projector

Open Question

I have the Epson Powerlite Pro Cinema 7500 UB projector. I recently noticed that when the screen is black, I have a few color specs on the screen. I just knowticed this 2 days ago. Prior to that it was fine. Is that caused by dust? I did about 2 months ago have a bulb explode. Could it possibly be pieces of glass inside the unit causing the color images on the screen? Does it sound like I just need my projector cleaned or does it sound like I might have a major problem with my unit? Thanks' for your help!!!

SOURCE: blue dots in the middle of the screen

The image processor must be getting old and worn out. Call Epson or go onto their website and see if it is  a dDIY project or if you will ned to send it in.

SOURCE: epson powerlite s4 projector is pink

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 red color has gone out. The image is made up of red, green and blue images layered upon the screen. If the red panel has gone out then there is nothing filtering out the red light in the image. This causes a nice red hue to the whole screen.

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.

SOURCE: 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.

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

Dark pictures after a lamp change normally indicate that the lamp isn't aligned properly, or that it has been touched with bare fingers and caused a black mark, or it's an inferior (budget) lamp.

My epson projector center is blurry


Hello, if it's mounted you may have never adjusted the "focus" on it before. Just slowly turn the end grey colored lens one way or the other with a stationary picture such as the menu on the screen, adjust it to where the lettering is the sharpest.....tks

Red haze at bottom of screen


Shut down the projector and allow time to cool before the lamp is taken out to be examined for any dis-coloration. If so the lamp needs to be replaced, try to test using a leased lamp to confirm Also check for shift in the alignment of the lamp settings and also the Lamp alignment.
