LP70+ projects a dark rose/pink tint upon the screen

My LP70+ projects a dark rose/pink tint upon the screen. I just replaced the lamp and this does not fix the problem. Has the color wheel died? If so, can I order a new one and install it myself?

    I have the magenta color whenever a devise is attached. I have swapped out the cable and that didn't fix the issue. When I try to go and adjust the color in the settings menu the Color option is greyed out and unadjustable. Is there a hard reset for the equipment? Why would it lock me out of the color adjustments?

The pink tint produced by my LP70+ projector was not a lamp issue but a connectivity issue. I swapped the old cable with a good known cable and the tint went away.

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

LP70 lamp will cycle on and off in 3 min. intervals.


go into the menu and check the lamp hours. if it's over 2000, you need to replace the lamp. if it isn't, the power supply and/or ballast is starting to fail.

Lp70 flickers and color wheel chirps at the same time. It's worse with more white in the image. Colored screen shots or dark movies have limited flickering. No issues prior to hookup to computer (Infocus...


it's chirping because it's trying to keep in sync with the dmd chip. for the refresh rate, go into the menu and first reset the settings to factory default. if this doesn't clear it up, try matching the signal.

InFocus LP70 color problem


try resetting the settings to factory default through the menu. if there's still a problem, take the cover off. if you look from the back of the machine, inside on the bottom left, you'll see the main board attached by a large white plug. use something thin and non-metalic to push the bottom of the board towards the plug to tighten it. now do the same to the other side of the plug. this should solve it. if it doesn't, you need to replace the main board.

Projector gives off pink tint


when you have a tint on the projector its not a lamp issue, it is a connectivity issue you have to check the cables if they are connected firmly, or swap the cables with good known cables , if this doesn't help you have to send the projector to infocus repair center, since it is a DLP projector this may require engine /major repair

Infocus LP70 - It's all Green


A tinted image (whether green or another color) is almost always a symptom of a bad or damaged cable - or a loos cable connection. In your case, you'll likely need a new M1 to VGA cable (Part# SP-DVI-A-R).

Assuming that you've made sure that the cable connections are solid at both ends, there is a simple test to verify that this is a cable issue and not a costly projector issue. While the image is tinted green, open the menu. If the menu colors appear fine while the rest of the image is still tinted green it's the cable.

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