In72 does not power up. I think that it is a blown fuse. Where is this fuse located

if there are no leds lit on the top, then it's a power supply issue. open it up and check the fuse on the power supply (next to where the cord plugs in). if the fuse is ok, you'll have to replace the power supply. you can get parts from an infocus service center or send it to them to repair. either way, try they're really good.

Can't source or use any buttons on the unit or remote..

Sounds like a hardware failure. Have a technician look at it.

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.

Thanks for the reply :)


It could be the grinder or power board that is the problem, if it was my machine i should replace the grinder.

Try to set power to the grinder, look at the grinder to make sure what volt it should have before you by a new. If the grinder start when you power it then i think your power board must be replaced.

Let me know if i can help you more.

Best regards

Bulb failures

I experienced the same thing, only to discover it was the ballast that powers the lamp. I believe INFOCUS repairs for $390.00 per the technician that I spoke with on the phone at INFOCUS.

Hi TheMull

I also checked and the fuse looked fine , but I thought to myself why not take a chance and replace the fuse as this is a very cheap part , and it worked.

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.

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.
