Question about InFocus IN72 Multimedia Projector

1 Answer

IN72 psychedelic traces

Watching a scene with people moving across a dark background, there are traces following movement.

Rather than streaks, it is a series of ghost images or echoes of the movement that linger on the screen.

Anyone see this before?

    But did replacing the bulb solve the problem for rickrickie?

  • mherbster Mar 03, 2009

    I have the same problem and was wondering if replacing the bulb solved the problem? If it is the bulb would I have other distortions or would I have other issues that would pin point the bulb as the problem?

When watching television or movies it will randomly go dark and in the bottom left corner it will read "component setting up image." after about 5 seconds it returns to normal. This happens randomly....


the most inexpensive thing to do is to replace the cables, also make sure no pins are bent where the cables plug into the projector. it that doesn't fix it try refashing the software. if that don't work it 's most likely the main board.

Projector wont power up


Hello :

Check your fans, The projector will not power up if either of the fans have failed . A defective electrolytic capacitor in the power supply can cause the problem also . You could check the lamb also . If the lamb is defective that also can cause the problem .

good luck .

When I connect the IN72 to a Digital TV Terminal I see horizontal moving lines on the screen.


the resolution doesn't match. reset the projector settings to factory default and make sure the settings are correct, and if the projector can handle the digital signal. you can also try swapping the cables.

I have the InFocus IN72 with only 900 hours on the current bulb...recently I noticed the brightness is dramtically darker...I have no Idea why this is...


Take you bulb out to see if the bulb is defective in any way. If its darker then there might be a chance there might have a dark cloud toward the bell of the bulb.

IN72 Projector problem


My understanding when we purchased our IN72 2 years ago is that there wasn't any additional benefit for Cable box using HDMI since the IN72 does not transmit audio so using component cables for cable was optimized enough. We have our DVD player connected via the HDMI only. Possibly the transmission from cable box through an HDMI is not compatible audio is confusing it? hard to say. Cable HD channels look awesome thru the compenent cables, the max for IN72 is 480i anyway.

We've got 35 ft cables for all 3 hdmi, compenent, and that vcr one too and it's worked great.

Colors are distorting e.g. Blue streak across top of viewing field


unfortunately not. the discoloration is caused by the light filter getting fried due to excessive dust and heat. and you cannot purchase the parts individually. you'll have to replace the entire optical engine.

Infucos IN72 projector


Hi Ronnel

This is a common Mainboard failure on a Projector.

The unfortunate thing is that the Mainboard will either have to be repaired or replaced.

IN72


Try using a different cable.

If the response is the same on a different cable , then the Mainboard might be at fault - this machine should still be under warranty and the warranty will cover repairs.
