Without even a source I can see a pink / red haze on the right side of the projector and as it heats up, lines and distortion becomes greater, mainly on the right hand side of the picture. This is from the default Proxima screen. And is the same if I plug in a source (so its not a bad VGA cable)
- I have replaced the lamp, with no change (it was just as bright)
- Does not appear to be anything on or stuck behind the lens from what I can tell.
I'm concerned there is a image sensor problem any thoughts on exploring this more?
I also am having the same problem. at first it only showed up after the projector was on for about 15 minutes. Now I get a purple vertical bar on the right of the screen. I also get vertical green bars spread across the screen.
Does anyone have a diagram of how this machine is assembled?

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.
We can check if the problem is on the hardware(projector) itself or if from source(device connected to projector) try to turn on projector without connecting any other devices to it. If you can still see the pink line- try to remove bulb and reinstall it. If all fails and pink line still visible, there is a problem with projector. If no line is present- check settings and change input signals.
the light filter on the blue lcd panel is fried due to excessive dust and heat. clean out the projector with canned air. unfortunately, you cannot buy individual parts of the optical engine- you'll have to replace the whole thing. or live with it.
From your description, it sounds like an alignment problem. There are 3 LCD panels in the projector. Each one displays an exact duplicate image of the others except it's either red, green, or blue. Under normal conditions, the images precisely overlay one another so you get a sharp image. Due to age, heat, or vibration/shock(impact) it would appear that the red LCD panel has shifted a little, giving the "ghosting" effect. You'll have to have the unit repaired by a qualified tech. He'll have the special electronic equipment needed to align the panels properly. Before sending the unit in, try a reset in the menu. Sometimes, the projectors can shift the image electronically, using math algorithms which will try to auto-sharpen the display. Hope I was able to help!---Rick
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.
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.
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.
to adjust those mirrors, you need to power down, unplug, remove the top, remove the wires from the main board, remove the main board, adjust one mirror, reinstall everything, power up, see whatever difference it made, power down and repeat until it's fixed. it's quite a chore. if that's not the problem, you'll need to replace the optical engine (which isn't cheap) because they don't sell individual parts.
