I have a Hitachi CPX3021WN projector I rarely use and a few days back when I put it on there was a large pinkish purple blob on the screen. This blob starts from somewhere in the mid lower area and th


It sounds like there are some magnetic fields around your projector. Similar to what used to be degaussing in an older tube TV. Sometimes it may be that the speakers are to close to the projector or even the earths magnetic field that may be effecting it. Try turning the projector in a different direction and see if that helps your problem.

1,white spots appeared on screen,means the DMD is broken,you need a new DMD.
2,the projector running off after only a few minutes,means the Inductor (Sensing element),near the Color Wheel. Use a cotton swab moistened with alcohol to wipe the Inductor.

White pixels forming on screen and increasing in number. Slight distortion in other spots pixels are extremely bright but small.


This is a problem with the internal DMD chip which needs to be replaced.
Contact BenQ Service,should be covered under warranty.

I have a panasonic pt l500u, just started getting large yellow spot in middle of screen- looks like a giant finger print. Bulb was replaced less than two months ago.


Hi:

The problem here is the one of the miniature LCD screens in the unit is faulty, in this case its the blue one. There are three of them inside the unit RED<GRN<BLUE. The blue seems to be failing in your unit, for instance if you mix red and green you get yellow. Have a local shop service the unit and clean and refocus the unit back to factory spec's..

Large dot in the middle of the projected display


there is a burned-in spot on the polerizer light filter for the blue lcd. it makes sure the light is blue coming through, that's why it is black on a blue screen, and yellow when the red and green are the only light showing through. it needs to be replaced. pat # PFiLW0213CEZZ.

Yellow middle, Blue Exterior


Hi Druaga

This is a Blue LCD Polarizer that will have to be replaced if the spot shows yellow.

You will find that this will only get worse as time goes by.

YELLOW SPOT ON SCREEN


There may be a dust fleck on one of the LCD screens inside your projector. I had a similar problem and managed to clean it. But it requires you to dissassemble the entire projector !!!. If you are not technical, don't do this yourself. !!!
