Question about InFocus LP 250 Multimedia Projector
Yeah i had same problem where the power would not come on. literally nothing, no green light, no power button, nada. I was able to fix it for under $20. I got a soldering iron from a friend, some solder, and a toolbox with a hexascrew or sectascrew or whatever it is that has six (i got mine from radio shack) starpoints. so basically took it apart which was complicated but totally doable. then i took off the top motherboard thingy and then was able to unscrew the power supply board which is about 2 inches squared. taking this off i was able to look around on it and visibly see one of the circuits on the bottom was blown. so i just re-fused it with the soldering iron. it was the first thing ive ever soldered and i was capable of doing it so it cant be that complicated i guess. anyways, that got it working again. didnt break anything to open it so why not give it a shot?

It's most likely the Power Supply in it which is blown...There is 2 Power supplies, one for the lamp and one for the board. The one for the board is always failing on LP240s. You may power it using an external Computer PS (+12V, +5V, +3.3V) and a +16V PS. I did it, and it is working perfecly for 1 year now.

Is there any LED lit or flashing when you press the power button? That can be an indication of a problem with the lamp. If the lamp hours exceed 2000, the lamp will not light until the lamp hour counter is reset. Also if the lamp door is not closed, the lamp will not light. Finally, a defective lamp will cause similar symptoms. There also may be an internal fuse for the projector, but changing it normally requires disassembly of the projector. Another thing to try is to use the power button on the projector's remote if it has one. I worked on a Dell projector that had a faulty power switch but would still turn on with the remote.

There is a source lock and source button I would unlock source lock button and the push source button until you get to your hdmi input you are using. You also may just plug in one input first and once you get the input right play with the multiple hdmis
