20 Most Recent InFocus Proxima UltraLight S520 Multimedia Projector Questions & Answers

You will need a VGA cable that can connect the projector to the laptop. This is usually the same cable that connects a monitor to a desktop computer.

Once you have the two connected, you will have to tell the laptop to send the video signal down the cable. This is normally done by pressing the FN (function) key on the bottom row of the keyboard, and the F8 key on the top. It will normally cycle through the following modes: laptop only (default), external, laptop and external.

Hope this helps and good luck.

you will need to get an RS232 compatable remote and wire it together

usually this will only control power on and off and not much more

this is usually done only in commercial set ups are you using it at home or work?

you would be best off getting a pro to install and load/ write code for you

When the lamps are replaced, you need to ensure you have screwed the lamp assembly into the cavity tightly. The lamp assembly presses against a tiny micro switch - if it is slightly loose, then this might trigger a malfunction when the unit is moved.

Other possibility is, perhaps the micro switch is faulty.

there is a burn spot on one of the light filters located next to the blue lcd panel. it is caused from excessive heat and dust. unfortunately, you'd need to replace the entire optical engine because infocus does not sell individual optical engine parts.

if the fans run, then ,check the lamp or lamp ballast
turn on the projector ,at the same time ,if you can hear a continuous beep beep sound (the ballast igniting the lamp)
means the lamp may be fault,and other parts is working well

Probably damage to the LCD or lens due to an old lamp that produces too much heat. If on the lens, clean it carefully with isopropyl.
