Question about InFocus X1A Multimedia Projector

InFocus X1 power problem

Had an X1 at one of my schools that wouldn't power on, no led, no fans, nothing. I took it apart and found that the soldered in fuse on the circuit board parallel to the power supply circuit board had popped. I replaced that fuse and the unit powered on for the first time. But the replacement fuse popped right away. The popped fuse was a 1 amp 250 volt slow blow fuse which is what I replaced it with. So, I'm wondering if this a common InFocus X1 problem and what the solution is or if I need to to track down a bad part on the circuit board one by one.

Something blew the fuse the first time. if it blew again, the issue remains. something may be arcing. check near the plug, or if there is anything bouncing around in there or a crossed wire.

Infocus x2 fan for lamp wont turn on


if there are no leds lit on the top when you turn the switch on, you have a bad power supply. if the leds are blinking, check your lamp door switch. if it's not closed, nothing will turn on.

The bulb on X1 blew out, I replaced the bulb, the


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.

Infocus X1a no picture, solid green LED


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.

X1 projector's fans not working


if the fan is not moving but still receives voltage, just replace the fan. if you're sure the fan works but no voltage, hope you're good at soldering. you need to remove the main board and solder a jumper from the bad fan's power and ground to the working fan's power and ground.

Unit will not Power Up.


Terry, I had the same problem. Its a small capacitor on the power board labelled 'C16'(right in the middle of the board) its value is 16volt 100uf.
I also changed the biggest one on the board as well( 450volt 270uf @85deg). The big one was sourced through RS components @£5.14, the other I got through a maplins store for the grand sum of 13 pence.
Both are quite easy to change if your not adverse to taking the unit apart. (Just remember where all the leads plug in).
A torx T10 screwdriver, and soldering iron is all you need.

Fan noise loud, bulb burst. Replaced with new bulb. Noise even louder! Unit shuts itself off.


the bulb may have burst from overheating from a fan not working to cool it down. and it can be replaced. it does take, however, a while to replace it because you have to take half of it apart. but make sure it's the fan first. take the lamp door off and remove the lamp. use something small and thin to push in the switch that the lamp door usually activates. turn the projector on and see if the lamp fan and the colorwheel (the multicolor glass disk) are spinning. if the fan spins, the noise may be from the colorwheel motor going bad. the fan can be purchased through an infocus authorized service center. check the website for the closest one. but the colorwheel for the x1 cannot be purchased seperately from the optical engine, and that costs a fortune. but here is the part number for the 80mm fan- 526-0152-00.

Infocus x1 noise problem


the colorwheel motor does burn out after a while (from heat and dust), but as long as it spins at the right speed, you won't see a problem in the image. if it's making noise, it's going to go soon. it does need replacing. however, infocus does not sell individual parts for the x1 optical engine. you will need to replace the entire engine, which costs up to $2000. so, enjoy the last few hours with your machine and look into getting another.

I want to test my infocus lamp to know if it is burnt


Your lamp might be ok, but you power supply is dead. If your not seeing any led lights come on when the power cord is plugged in then your power supply is dead. I can fix this for you for less then it cost to send to infocus or to a repair shop. Ebay Id is Gtitubro

Infocus projector power supply dead


the caps dry out. look for bulging caps. you won't find a schematic for the ps boards. infocus had someone else make them. the problem seems more like a overheating issue. as for the other one with the "just the fans", check the colorwheel.

Infocus x2 dose nothing


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