There is a fuse on the power supply, right on the power cord socket, but you need to remove the cover. but test this first: are there any leds on? if yes, it's not the fuse. check the lamp door and the filter cover on the bottom. it could also be the lamp is bad, the ballast is blown, the fans have stopped, the thermistor is blown, etc. if there are no leds, it could be that the power supply is bad. if you want to tackle this: remove the 4 bottom screws, then lift the top from the back, carefully remove the ribbon cable fron the main board (slide the cable locks on either side of the cable towards the front of the projector to unlock it first), unplug the wires in the front, and slide the lid forward over the lens. remove the main board off of the top (removing the 3 ribbon cables, all other wires, the cable nuts off of the back, and a few screws). the power supply is on the back side. if the power supply is bad, you can buy one from an infocus authorized service center (check the website).

Infocus sp5000 wouldn't turn on. i replaced the bulb & it worked fine it won't turn on again. i screwed the lamp cover back on tight so don't think it is that.

take the lamp cover off.
get a toothpick and push it down where the cover operates the swicth and check that it clicks on and off properly.
check the air filter cover as well

I have an InFocus SP5000 that the DVI port isn't working on. How can this be fixed or is it worth fixing.

what's wrong with it? if you are not getting a signal, first swap cables, reset the settings to factory default, and make sure the resolution matches the source. if all else fails, send it in to an infocus service center. it may just be a plug issue or a cold solder joint. at the most, you'll have to replace the main board (which would be about $500 plus labor). try av solutions in ny. they're really good.

there isn't a colorwheel in the sp5000. it's an lcd, not a dlp. one of the fans is bad and needs to be replaced. the bearings might be going. you can get parts from an infocus service center or send it to them for repair. try av solutions in ny. they're really good.

I have an Infocus SP5000. The unit turns on,but

I use an infocus for my church. I don't believe there is a counter shut off, or a reset that would revent the light from operating. I sugest you go ahead and replace the lamp.

Infocus sp 5000

if there are no leds lit on the top, check the lamp door switch. if the switch is bad or isn't activated by the door, it won't turn on. and there is a fuse on the power supply, but chances are, it's the power supply itself that is bad.

I have an InFocus SP5000 projector that has started showing a green glow in mid-screen (center). Before I buy a $300 lamp want to know the cause of the green glow.

either the light filter behind the blue lcd panel or the fly-eye lens (both inside the optical engine) have developed a burn spot from overheating. infocus doesn't sell individual parts for the optical engine, and the whole thing must be replaced. but unfortunately, it's the most expensive part of the projector, usually upwards of $2000 (and there's none in stock).
