Question about InFocus LP 240 Multimedia Projector

1 Answer

Infocus 250 will not turn on at all.

Tested power source--that's not the issue. No response to power button; no fan noise, no lights, no nothing.

    I had a similar problem (after repairing the power supply problem), turned out to be a loose connection from the DC power supply to the Bulb assembly. The cable is at the front of the board and the connection is next to the remote sensor lense.

Infocus projector makes a whistling sound then shuts off


The whistling is nothing but noise. You need to open the projector to confirm the source of noise. It can either be mechanical or electronic. Possibility of mechanical noise sources are colour wheel (a 4 colour wheel near the lamp), blower fans & exhaust fans. All these are rotating things. If any one of them is jammed, then so as to try to rotate at full speed creates noise. To reduce mechanical noise it is necessary to service them. Dust is one of the main reason. For electronic noise check SMPS (Switched Mode Power Supply) & lamp ballast (electronic choke).The electronic noise is a high frequency noise generated by such devices. Are you using the projector in dusty envionment?

My infocus IN1 projector won't turn on anymore.


Hi,
It may be the lamp is out. Normally a projector will try & fire the lamp 3-5 times then shut down with a different color light like amber or red. If the lamp doesn't light then it could be the lamp or perhaps the lamp ballast that starts the lamp has failed. A stuck fan also causes similar symptoms. There's 2-4 fans in the projector if one is stuck or bad it will turn off within 5 seconds or so after the lamp lights.
Does your lamp light at all? Are the lights a different color after it shuts down? Answers to these questions help figure out what's wrong though it's impossible to say for sure without looking at it. I service almost all Infocus projectors if you would like a quote please reply with your email address or write me at prmhelp@earthlink.net
Good Luck,
Jim

Infocus X1a LONG startup times


Sounds like the power supply is weak if it has to run for awhile before it functions. The control board could also be the issue. Does it make any grinding or buzzing noises?

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


Hi LuckyLindy

Next time this happens , just take out the main connection to the Mainboard and plug it back in.

Also remember to reset your lamp timer now that you have replaced the lamp !

Only power button responds, nothing else


Hi there

This unit should still be under warranty - take it to your nearest InFocus dealer.

If no signal is picked up then the Mainbaord is faulty.
