Sanyo XU50A will not recognize any input

SOURCE: 3M MP7740i Projector no input is detected

Hi mrus821

If the signal won't go through you will have to either have your Mainboard Repaired or Replaced.

This is unfortunatelly a common Mainbaord problem , and the above is the only way to get it fixed.

Hi BEEZELLE

Does the VGA input work ?

If not then the Mainboard is at fault and will need either repair or replacement.

I had the same and it turn out to be that my VGA cable was broken

The Fix Ya rep suggested that I try the "Reset" button located next to the Audio out on the side of the projector; this solution proved to be the fix I needed. I was able to get the lamps to warm up and get into the menu to cut back the bulbs/power consumption on start-up, allowing the projector to function for a problem-free 4 hour period Unfortunately, I had the same issue this morning, but the same fix worked again.

I had the same problem and the technician diagnosed as being caused by a faulty Ballast which he said caused the bulb to fail. He didn't test the bulb but his experience indicates that even if the bulb was not blown it would have been stressed and it would only be a short time before it fails completely.

When these fail there is no real reason for it it seems but it has been suggested that a probable cause could be not cleaning the filter, at least every six months. The result of a dirty filter would be overheating and this could be the cause of the failure.
