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

While watching my sharp dt - 510 projector the picture changed to black & white and start to jitter.... color has not returned after restart...60% bulb life used...


That will happen as the projector loses syncronisation with the in coming video.
Check the leads and connectors for poor contact. The lamp will not give that effect.

LCD projector not displaying color only black and white


Did you ever see color on this projector?
It could be the composite input cant detect the "color burst" 3.58 mhz signal for chroma.

Have you tried a different input?
That could help you track down what the problem may be.

Abnormal picture


if it's an xr-32x (as it shows on this pic), it's a dlp projector, not an lcd. therefore no green filter. it has only a colorwheel and a dmd chip to affect the color. if it's not an xr-32x, and it's an lcd projector, replace the green filter. sharp sells the parts for the optical engine. but if it was your service tech that did it, have them replace it.

Benq 7220 display wrong color


It sounds a lot like a bad color wheel if it was a DLP. IF it is a LCD then i would say one of the LCD panels is bad or possibly a connection problem that drives the panel or the connection that hooks up to the projector is suspect. Let me know if that helped you at all.It is strange that the bottom shows white though. Jay

Lg 32lc2r, only showing picture in black and white


Make sure that the color control level is set to the default or 50% to start with. This should be in the Video menu.

The colour for the tuner and for the encoded base-band video uses a circuit area called the colour demodulator. It is possible that this cirucuit area has failed and needs servicing.
