Question about InFocus LP 250 Multimedia Projector

1 Answer

InFocus LP 250 Multimedia Projector was working fine until i unplugged it and when I went to plug it back in, I used my computers power cord instead of the projector but the plug is almost identical. I thought that might be the reason and if so how do i fix it? It was unplugged for maybe 48 hours before I tried to turn it back on with the wrong cord. My questions is, could using a desktop computer power cord fry something in the projector?

The plugs on this model projector is very delicate, over time the solder around the plug will begin to crack. Until eventually the connection is lost. Another possibility is that the power supply has gone bad. Using another cord would not cause this. I can fix the projector if you'd like. My ebay screenname is gtitubro.

I actually have a 250. bulb is new but stopped working. When plugged in green power indicater lights then flashes two red lights.


The projector is bloked, you need reset the lamp timer. Press and hold the VOLUME + buttom, then press the VOLUME - buttom. Hold both buttons down for 10 seconds.

I have two InFocus LP 540 projectors that simply do not indicate power when they are plugged in. Has anyone else experienced problems with the power supply? Is there a fuse somewhere that might need...


you can check the fuses (located on the power supply board where the cord plugs in), but it's more likely that the caps are dried out and need replacing, or the whole board itself. if that's the case, try av solutions in ny. they're an infocus service center and they're really good. www.avsolutionsny.com

power supply is bad and needs to be replaced. unfortunately, there are no parts for this model. infocus no longer sells them, and they were made by another company that no longer makes power supplies. therefore, no schematics either. sorry.

Connecting Dell laptop to Infocus LP820


The USB cable doesn't transmit Video. You need to plug in the VGA cable. The "DVI" port on the LP820 is not a a DVI but a M1 Digital port and won't work with DVI unless you get a converter.

Projector stopped working


Hi amp422

This wouldn't be a lamp issue at all if there is no power at all on the unit.

Take of the top cover and change the fuse located on the Powersupply Board ( the one where the AC socket goes into)

Should do the trick.

Thanks for using Fixya !

Infocus 250 projector won't power up


Urinate on the bulb. This sometimes lubricates the contraption that the bulb connects with and it usually comes on instantly.

Infocus LP 600 will not power up! It is not the cord or the outlet. Thanks Paul K


Hi Paul

Does the counter on the LCD display ontop of the Projector work ?

If it doesn't your Powersupply board will need replacement.

If the counter does work , it is either your lamp or the Ballastboard ( lamp's powersupply) that is faulty.
