Question about InFocus SOFTCASE, LP425Z Multimedia Projector

2 Answers

Problem with INfocus LP425z Colorwheel ?????

I have had this projector for 6 years and have used it less than 50 hours. When you turn on the projector the fan turns on and about 5-10 secs later you hear a whining noise and then the lamp turns on. Two years after purchasing it, it would take a few times of turning it on and off before the whining would start and the lamp would light up. Now (RIGHT BEFORE SUPERBOWL) theres no whining or light. I was told by tech support that the whining is the colour wheel. The lamp should still be good with less than 50 hours used. Is it easy to open and look at the Colour Wheel?

Even if it is the colorwheel, you wouldn't be able to get a replacement. infocus no longer has parts for the lp4xx series.

That unit has a bearing color wheel, if it was not stored proper, it could be sticking. That would explain the power cycling. giving it a bump start if you will. Yes you can open and inspect to see if color wheel "free wheels"

Infocus lp425z projector pushes latop display to left quarter of output image

Usually this is a hardware acceleration setting problem on the 'advanced' properties setting in your 'screen resolution' properties on your computer. Re-set the hardware acceleration to the 2nd setting and this should fix your issue. We have this regularly when we project on a double projector system and the one projector keeps shifting everything left until we adjust the hardware acceleration settings on the computer. No more issue.

Replaced bulb. Worked for a while then wouldnt power up again.

the cheew cheew cheew is the colorwheel not spinning properly. either the colorwheel motor is shot, the sensor can't sense it, or the power to it is too low. first thing: remove the cover and blow the dust out of it with canned air. dust does a lot of damage to these. if it is the sensor, cleaning it off might help. if it is the colorwheel, i have bad news: on the x1, the colorwheel is not sold seperately from the optical engine. you'd have to get the entire optical engine. now the worse news: infocus no longer makes or sells parts for the x1. you could try and find one on ebay that has a different problem and swap out the parts

With all menu settings appearing with their normal values, my X2 projected image ''oscillates'' between showing correct colours and a heavy green overcast with no blues or whites. The green light is steady...

your colorwheel is going bad. needs replacment. find an infocus service center and purchase part # 525-0144-00. shouldn't be more than $50, but replacement is pretty involed. you need to remove the top case, front and back covers, power boards, plate, lamp house assembly, and fans just to get to where the colorwheel is plugged in to the main board. removal of the actual colorwheel is only 3 screws.

?blown bulb

do you hear a high pitched whir or chirping? the whir is normal. the chirping is the colorwheel not syncing with the dmd chip. this will cause that image distortion. if the colorwheel is fine, then it's the dmd chip of the chip pcb that needs reseating or replacing.
