Did you use a genuine bulb ? Clones perform very bad.
Problem can be also inside the ballast unit ( lamp supply)
These units should be replaced completely, repair is even for experienced technicians 100% impossible.

firdt off, did you reset the lamp counter? did you clean the dust out of the projector? it may be overheating as well. if the lamp looks ok, you may have just blown the ballast. try projector doctor online.

I have a Sanyo PLC-EX20 projector which shuts down after five minutes, what could cause this?


There are 2 possible causes.

The first may be due to overheating. Most projectors have a "air filter" that can be removed and cleaned. If it gets clogged with dust over time, the projector can't breathe and shuts down.

The second cause may be your lamps life hour clock. Most projectors keep track of the amount of time that their bulbs have been active. Once a preset # of hours has passed the projector will limit functionality until a new bulb has been installed AND the lamp life clock reset. Most projectors do not automatically reset the lamp life clock after a new bulb is inserted.

There should be instructions on how to reset the lamp clock in your users manual, and info on cleaning the air filter. Unfortunately I went to the Sanyo website and was unsuccessful in locating a PDF of the user manual for you.

This projector, almost since new, turns the lamp on for about 15 seconds and then the lamp shuts off. I have taken it to 6 technicians here in Uruguay, and none of them know anything. If the unit is left...


there is a problem with the power to the front fan from the main board. there are 3 wires going to the fans: one power, one return, and one signal. if the main board reads no signal from the fan's speed, it'll shut down. check the power going to the fans and the signal. you may need to replace the main board.

Mistub XD450. Bulb relatively new. Projector


Does the projector work normally when sitting right-side up? If yes, something could be interfering when the unit is inverted. The symptom you describe initially sounds like a defective fan (some fans put out a computer pulse telling the main board it's running--they have 3 wires, red, black, yellow(signal)). If the board doesn't get signals from all required components, it's programmed to shut down to protect itself.

Lamp does not come on


For the time being at least, I got my projector back on by unplugging the power cord for about 30 seconds then held down the following keys on the projector: Menu, Enter and the Down Arrow and while holding them down, pressed the power key. The projector started up like new with H0000 hrs on the screen like it was a new one. Will be interesting to see how long the bulb lasts! I had been getting a Replace Bulb messge for several weeks before it shut off with two red lights lit. So I tried the above procedure befoer buying a new bulb.
