Question about InFocus Rear Foot: LP330, LP335 Multimedia Projector

InFocus LP335 units with no power lights at all

Hello,

I have three InFocus LP335's that I bought off ebay so I could use the bulbs for my LP330. However, my LP330 is now flickering a bit, so I am hoping to resurrect the LP335's for backups and possibly for the increased lumens.

When I plug in the LP335's, there are no orange or green power lights AT ALL and no fan noises. Nothing happens when I press the power button. I have tried different bulbs and opened the cover to make sure that the connector from the button/LED module to the main board is connected properly.

Can anyone think of anything I could try?

Thanks very much!

Rich

Try concluding that your LP335s are junk.

SOURCE: Infocus LP350 won't show signal, also panel buttons don't light up

Yeah, strange enough the lamp timer was already reset. I think whomever had this projector before me had tested it before selling it. Thanks for the response, though!

SOURCE: 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.

SOURCE: wont light up

the colorwheel needs replacing. if the colorwheel won't spin, the lamp won't light. if you hear a high-pitched whir, the colorwheel works, which means there is a power supply issue. there is a fix for that, but you have to be good at soldering. if you are give it a try: http://www.infocus.com/service/asc/communications/tech_notes/2006/09/tn495g.pdf

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

InFocus LP650 will not come on


First try a firmware upgrade. If that doesn't help, it seems it might be a power supply issue since you said the led comes on very light. I repair these power supplies. My ebay id is gtitubro

Infocus IN72 powers up but no image, replaced the bulb but still no image...


Hi there

This is most probably a Ballast ( lamp's powersupply ) problem.

Make 100% sure that this unit is out of warranty because InFocus Projectors come out standard with a 2 year warranty.

That color is not listed because it is either Green or Red. There is no Blue, if you are getting Blue, you have something that is extremely unusual.

Black lines are appearing on the top and bottom of projection,.


try factory reset in the menu. if that doesn't help, it could be the light tunnel, but infocus doesn't have parts for the lp3xx series anymore.
