Wire loose inside handset, or receiver output problem. wiggle the handset wires and listen for crackling. if so, repair or replace.

Sounds like the DMD chip is on it's way out.
Check if the intermittent problem is related to the external air temperature. Try blowing cold air around the unit with a personal fan to see if it does the same thing.

Projector is completely nonresponsive. Almost like it has no power. No lights on, etc. Yes, power cord is plugged in.


There is an internal fuse that may have blown. I urge caution however, as this fuse does not open without a reason. It is possible that a power supply problem is preventing the unit from starting up as well. Usually though, this would show at least a standby light. Unless you have previous experience with the repair of similar units, I would not suggest any attempts now. There are potentially dangerous voltages present inside these machines.

Please update this if there are any sympoms at all when you attempt to power up the unit.

Thanks,
Dan

The countdown shows while the unit is going through its internal circuit testing. Usually if a problem is found, there will be indications with the standby lights and lamp/temp lights. Are there any other indications here or just the unit going into standby?

I have 2 new Epson 84 projectors and they are both showing 3 solid orange lights. What does this mean - I called Epson and they have no idea. :(


If they are new and Epson has no idea what the lights mean then return them to where you purchased them within 30 days. If it over 30 days Epson will exchange them or repair them at no cost.

Infocus X1 picture freezes and dissapears and then comes on again


your display settings may be off, so change settings to factory reset and you may have to drop the resolution on your computer. you may also have a bad cable, so try a different cable.

Flashing red Power light, but unit won't start


I had a similar problem, but with no lcd lights showing 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. Perhaps you will have to check the ballast for problems

It sounds as though the unit is overheating. That would explain why the fan keeps running, and once it cools down enough it starts up again. What kind of environment are you running this in? Is there a way to put it in a cooler environment? Even having an external fan blowing on the unit could help. Honestly, unless you've got it in a very hot environment, it also sounds like a poor design for heat dissipation. Or possibly the heat sensor is bad, and shutting it down at a lower temperature than it should.
