Most likely a bad cable. Try bending a little bit of the wire at a time and see if the color flickers back to normal, or you could just by another cable and see if that fixes it. Happens to a lot of the projectors I support.

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

Hello, My projector has approx 400 hours of run time. It will not project any hues of red. Any suggestions?


Does it show red hues without any devices connected to it? If the colors are fine without an input device, the problem is your cabling or a connection. To check these, do the following:
1) Disconnect all your cables and observe the ends to make sure they are undamaged. If they look good, reconnect them.
2) Flex the cabling, moving a few inches at a time, starting at one end and moving slowly to the other while watching the projected image. If you see any change, you have found a damaged cable and need to replace it. If nothing is found, then try step 3.
3) Replace your cables with any spares you might have. If this does not fix the problem then go to step 4.
4) Go into your projector menu and find your color settings. Try adjusting these to see if you get the red hues.

If none of the above provided a helpful solution, The problem is usually the internal color panel. The last time I had one of those repaired it cost about $2000. If you are not very experienced repairing electronics or electronic components, you should not attempt this.

Picture has green tint


This is most likely an issue with the cabling. Check that all the cables are inserted correctly and display a picture you are familiar with. Try "wriggling" the connectors as you view the image to see if there is a poor connection.

The problem could be that one of the LCD's is dying and thus affecting the hue.

Hi Larry

Try using a different RGB cable , if this doesn't fix the problem you will have to get the Mainboard of the Projector either repaired or replaced.

Dlp color whel glas


The projector is easy to open. whole side comes off including half silver bit at top you need to search for little rubber dots about 4mm in diameter, pick them out with a knive then undo the screws you will also need to remove one of the hex screws that the vga cable screws into. will not hurt to remove both, just use some pliers to loose them. Also remove the bulb door.

A blue hue


If color correcting does not fix the problem you will probably need some professional equipment in order to fix it. It would probably be best to contact a professional service provider.
