Question about Epson LCD PROJECTOR, XGA, 3500 ANSI, 1024 x 768, 450:1 => Model POWERLITE 7850NL Monitor
When i start it up it makes a very loud noise for about 2 minutes. I cleaned all the filters. That didn't help
a 6ya expert can help you resolve that issue over the phone in a minute or two.

You have not set the port on the back of the projector settings.
Go into the projector menu and go into the IMAGE area. Somewhere in here you should be able to select computer.

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.

I've got the same problem on two Epson EMP7300.
I believe (from reading about other projectors) that the ghost image can be adjusted with RS232 codes.
Does anyone know how to do this?
