''Infocus Demonstration'' logo at upper right hand corner screen
The logo is present as the movie is playing. If you select menu it goes away. As soon as you go back to the movie the logo comes up again. I have done the following. Call infocus tech no help there, Factory reset, Firmware uploaded. Nothing helps. I would like to know if any one has rest codes for the hardware of the infocus sp7200.

Re: ''Infocus Demonstration'' logo at upper right hand...
No reset codes, but the problem lies with the dmd eca, which is the circuit board that attaches the dmd to the main board. this board holds the splash screen ("infocus" screen) info. unfortunately, unless you have the specific part number from the board, you need to replace the entire optical engine, which is the most expensive part of the projector. if you do get the part number, find an infocus authorized service center and purchase it from them.

your light tunnel has collapsed and needs replacing. you can get the part and do it yourself, or you'll have to send it in to an infocus authorized service center. try av solutions in ny. they're pretty good.
the light tunnel is collapsing. it's used to hep evenly distribute the light and make the edges crisp. infocus now calls it an integrator rod (315-0055-xx).
to replace the tunnel (rod):
take the top off, take the screws out of the top and the wires out of the circuit board, take the fans out, take off the colorwheel shield, remove the lens assembly (optical engine), remove the colorwheel, take out the 3 set screws, and slide out the tunnel assembly. then remove the foil around the opening and the screw out of the top, and slide the rod carrier out. now remove the metal clip and the pieces of mirror. replace the tunnel (rod), put the clip back on, and reverse the procedure. now, the 2 set screws on the side are to adjust the image, so do not put them in too tightly, and they must be adjusted while the projector is on and the cover is off.
cover up the infrared remote sensor on the projector. The heat of these colours or something might be messinf with the infrared remote sensor. TRy this and see what happens. It may just be bad contacts. Some projectors just cant handle stuff like this. Some were meant for presentations and presentations only. BUt seriously try covering the remote sensor to see what happens. If it is an older projector the infrared signal detector might be sensitive to bright light or stuff like that.
