EIKI LC-XNB3 Projector - Does not recognize any Video Inputs

My EIKI LC-XNB3 Projector does not recognize any Vdeo Inputs, but works great when hooked up to a laptop. I have tried all three connections to my DVD/VHS player ("S" Video, Y-Pb/Cb-Pr/Cr, Composite Yellow) and I have tried to manually change the input selections through the menu. Is a circuit blown? Is there a blown fuse (and if yes, where?)
I am game to try and fix it myself, if possible.

There might be a bad connection between the input board and the main board. There are different connectors ( white) between them, that might be damaged during portable use

I have an eiki lc xg400 at my disposal. I have a toshibi vcr/dvd player. How do I hookup the vcr to the projector and is the hook up different for the dvd? Thank you De


this depends on the signal type coming from your sources

best is using component signal ( Y-Pr-Pb) , by using the right cables and right settings for video inputs in the projector menus.In basic this should be possible.

It sounds like it is overheating. Are the fans all working? If so, try opening the casing and blowing all the dust out with a can of air from Staples/Office Depot. If the fans aren't working you may need to replace them.

Hi there

First try another cable from the PC to the Projector.

The VGA / RGB Cable used from your PC to the Projector has a couple of very thin copper wires on the inside and they easily get damaged.

If this doesn't help then you should try another PC.

If that works then you'll know that it is the PC's card that is faulty.

If it doesn't work you'll have to get the Mainboard repaired or replaced , because the inputs on the Projector lies within the Mainboard.

Must warn you that a Mainboard replacement is a bit on the expensive side.
