Infocus SP4800 Distortions

I noticed you helped a few people with the SP4805 and I was wondering if you knew how to fully take one of these apart. I can not find a free repair manual for the life of me...

The problem I am having is there are a couple of spots where the color is slightly distorted (most noticeable on white where it has some gray spots) I figure it is some dust that has accumulated on a lens of some sort as that was the problem on other projectors I worked on with the same problem. But I can not get the thing fully open.

So my question is... do you agree that is the problem? and if so how do I get that thing open. I can send pictures if need be.

With the image shown, use the lens to focus on the spots. if you can, it is dust. if you can't, you have a colorwheel issue. to take the top off: remove the 8 screws on the bottom (4 brass from the bottom middle, 2 silver from front bottom, 2 from rear bottom), 2 or 3 on the back. use a small flat-head screwdriver to undo the clips through the top vent on the back panel and remove the panel, unplug the wires fron the left and right sides, pull the top up and forward taking front with it. blow dust out with dry compressed air.

Infocus SP4805 buzzing noise


Hi dcabbarno

The buzzing noise is a broken colourwheel and the shadow could be a part of the colourwheel that is obstructing the light engine or it could be your packlight pipe ( tunnel with 4 tiny mirrors in it ) that was damaged when the colourwheel broke.

I do unfortunately not have the part numbers of the parts that I mentioned , but you could assist by opening up the unit and supplying me with the part numbers.

The colourwheel you will spot straight away once you've taken off the top cover of the Projector , the packlight pipe is situated right next to it - looks like a small tunnel that's got 4 mirrors inside it - takes the light into the light engine.

Once you've supplied me with these I can get you prices and places to order it from and will help you with instructins on how to replace them - it is quite easy to DIY.

Thanks for using Fixya !

Unable to switch off projector with remote (Infocus SP4805)


A bit unusual for the projector to stop responding to the remote. Usually it follows when someone has opened the projector, they forgot to reconnect the controls from the case top which also includes the IR receiver. If it isn't that, it could be a broken IR pc board or bad connection. I've seen that.

The worst case is that the IR controller on the main board has failed and if that's the case, you'll have to live with it as the cost of a new board is very high.

Powering down


I think you mean that you can still hear the fans running after shutting down, this is normal with the X family of projectors including the SP4800 and SP4805.

PLEASE HELP!!


It also depends what part you need because although the 3 models look similar none of the parts are compatabile with each other except maybe some body parts and the X1 and X2 share the same light tunnel but it would be a risk to assume that the light tunnel from a used model is OK. The only 2 models that share the same parts are the X1 and SP4800. The X2 is brighter and the SP4805 has a 16:9 native ratio.
