Fix pink and blue line/band on Epson projector
https://sites.google.com/site/troyinphoenix/

I don't have a solution but I just purchased the exact same thing which arrived a week ago and I have the same problem. I just have a blue shape in the middle of the screen shining through. I called SONY but they were closed for the day. Trying to find a solution on-line. Maybe we got a bad batch of lamps??

this discoloration is the begining of the lcd panel being thermal damaged. this happens when the projector is being used for a long period of time and then being shut off using the switch on the rear of the projector instead of the on/off on top or the remote. to fix it it will have to be replaced. very expensive major repair.

Take it back to where you bought it and get another one.

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.

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.

Guys, the projector doesn't do HDCP.  HDMI won't work.  You'll need to run over component or VGA.

Hi, please try to replace the cable, try another input source and reseat or replace the bulb . If issue still present upon doing those steps you may need to call epson tech. support at 562-276-1300 so that they can verify whether your projector is under warranty or not and give some great option regarding your projector.
