SOURCE: Duplicate image in pink displays on the screen.

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

My Epson EMP-S1 projector shows pink color with VGA input only, ok with video input and menu screen. What can be the problem?


With the VGA you have a bad cable or a bad input jack. I would bet on the cable first. You are missing the green or the blue on the screen and that is why the red/pink is more pronounced now.

Sharp XR1S It projects the image on screen, use to show the correct color. last time the image was projected but in pink hues. is this an adjustment issue or is the lamp going or gone?


hi,
first of all check the tint setting on your projectors picture menu.
if not get the correct color then, your projector is a dlp projector that means it have a color wheel in side. if the synchronization of color wheel is not correct this problem can occur. there is a sensor for couting the rpm of color wheel. also have a black mark on the color wheels rotating portion. the sensor scene this black mark for making count. if there is any dust in that portion it will make difficult to the sensor making the counts. you have to remove the color wheel to clean the same.
i have added a video how to clean the color wheel . not the same projector.
ok

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.

Sharp Notevision XR-10S Multimedia Projector shows pink on the screen


Hi there

If the colour only shows pink when a source ( i.e. vga or video ) is inserted. Firstly check for a faulty cable - 99% it is the problem. Otherwise you'll have to take it to a repairer as the input could be damaged.

Permanent Coloured tint


When the image turns pink, we find that replacing the cable between the projector and the lap top fixes the problem.
