Infocus projector power supply dead

make sure the colorwheel is spinning. if it is not, replace it. also, blow the dust out of it with canned air. excessive dust kills lamps quickly. you'll also need to reset the lamp timer. are you using an sp-lamp-009? the sp-lamp-018 looks exactly like it, but is used in th x1a and x2. the x1 only uses the sp-lamp-009. if all else fails, replace the power supply.

it's the fan. if it won't spin full power, it can't cool down the projector and it'll shut down. there are 2: 60mm (part # 526-0153-00) and 80mm (526-0152-00). both can be purchased from infocus or an infocus service center.

if the lamp is new, it could be the power supply (the ballast is built in to the ps). but make sure you have the right lamp. the X1 and X1a have an sp-lamp-019 and the similar X2 and X3 have an sp-lamp-018. the lamps are almost identical except for the wire configuration on the lamp plug. make sure the wires in the plug match the positions in the socket. also, when you turn it on, if you don't hear a high pitch squeal, the colorwheel is not working. and if that isn't working, the lamp won't either. also check to see if the lamp door is closing properly and hitting the switch at the top of the opening.

fuse on ac filter board. if that's ok, there is a power supply issue.

pls send the tunnel photograph

you won't find schematics for them. infocus had their boards made by someone else who now no longer makes boards. it's usually the caps drying out that causes power problems.

you have to go to an infocus authorized service center. you may be able to purchase it from them without having them put it in. check the infocus website for an asc. but for reference, the part # for the ballast/power supply is 520-0126-00 if there is a "0" in the 5th to last position in the serial #, and 520-0143-00 if it's an "a" in the 5th to last position.

It also depends what part you need because although the 3 models look similar none of the parts are compatabile with each other except maybe some body parts and the X1 and X2 share the same light tunnel but it would be a risk to assume that the light tunnel from a used model is OK. The only 2 models that share the same parts are the X1 and SP4800. The X2 is brighter and the SP4805 has a 16:9 native ratio.

ebay has several that need bulbs... just a thought here is one of the item numbers Item number: 270207032811

Assuming the power outlet and cable is OK the most likely problem is the power supply and needs to be replaced.
