Video and data projection


A fairly symmetrical yellow (or other color) area is appearing in the center of the image of my projector. It seems to slowly be increasing in size over time.


Stop using the projector immediately! This is an indication that one of the polarizing filters in the projector has been burned in the center. If you continue to use the projector this way, eventually the LCD panel itself will be burned. Polarizing filters are drastically less expensive that LCD panels. Send the projector in for service as soon as possible to prevent a much more expensive repair bill.
