Question about Epson PowerLite® 1700c LCD Projector
I have dual projectors in a small auditorium. The image on one of the projectors has a green circle in the middle as if someone is shining a spot light on the screen. I have replaced the lamp but the spot is still there.
Welcome to LCD 101, the blue device is dying in the projector. Replace product with dlp brand and it will last a lifetime. good luck

Probably the filter is blocked. Unplug the power lead at the back and leave for about 30 seconds. Plug back in and it should work. The first opportunity you get, buy some compressed air and give it a good clean.

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.

My guess is that you have the projector flat on something? I did that and got the spot right away. The directions says NOT to lay flat, you must use the arm/handle so it will not overheat. Next time you get the spot pick the projector up and it should go away in about 10 seconds. It is overheating. Use the arm/handle, if you need it to sit level place a wii game or something similar size in the back to level it out.

you have a fried polarizer on one of the lcd panels due to excessive dust and heat. may need to replace the whole optical engine.
