Question about Sanyo PLC XU50 Multimedia Projector
Our projector shows a "disorted" video image (B&W instead of color, squiggly lines) and then shows the blue "no input detected" screen when in the VIDEO mode. It then powers down (flashing red lights) after about 2 minutes (NOT the "NO SIGNAL" countdown, it powers down on its own.
In the laptop/computer mode, it will display the computer image perfect, however it will also power down on its own after several minutes. Again, no warning, no countdown, just flashing lights until the fan stops blowing.
This would appear to be a bulb that has reached end of life -- or the projector thinks that it is because of hours. Usually most bulbs are 1000 or 2000 hours. Depending on your projector there are different ways of checking bulb life hours -- if you Google your projector model number and "bulb life" you will usually get a post on how to check these hours. Also, if it is a new bulb and you haven't reset the hours counter, it may need to be reset (however you also don't want to wait too long before changing a bulb that has reached EOL since they can and do explode sometimes taking out the projector with it).
