Hi there

I take it the Projector is ceiling mounted ?

If this is the case check that it is installed with the lens of the Projector in the facing straight to the middle of the screen or try adjusting the bracket's swivel head to move it a bit - should do the trick !

You have to open the LP750 and check the alignment of your color lenses. You might be needed to adjust, also check your lamp too.

reset the settings to factory default. if that doesn't work, you may need to have the eca controller (main board) replaced. unfortunately, infocus no longer carries parts for that model anymore.

It does sound like this is an alignment problem of the blue LCD or a problem on the main board controlling it. I am not sure if this is a field adjustable unit. A call to the authorized service center should provide that answer.

sounds like you have ghosting, this is not adjustable unless you can get into the hidden menu and then you have to know exactly what you are doing. Or the LCD ribbons have come loose. The easiest thing to try is reflashing the software.

MT830 Color Convergence (Blue Left - Yellow Right)


take a look here: http://www.extremetech.com/article2/0,1697,1049289,00.asp "... The others, however, have lost portions or all of their blue channels. TI's theory is that the shorter wavelength and higher energy of the blue light apparently causes the organic polarizing material in the LCD to get lightburn much faster. TI showed us a damaged LCD panel that controlled blue light transmission, and there was a large spot in the center that was apparently burned out..."

Convergence problem


We need a better description of what you mean by shadowing. However I am assuming: 1. You mean it ''bleeds'' off to the right when you have something with a hard red/blue drive. 2. When you turn the contrast and color down a bit it gets better. unfortunatly I cannot tell you how to fix convergence, but I can think of some other possibilities. In this case the red/blue emmision of the crt is dying off and going into saturation when driven hard. To fix, replace with a new picture tube/crt. In some cases you can get a little more life out of that tube (with a watchable picture) by having the screen, focus, cathode bias, and drives slightly readjusted. It will take someone with experience in doing these adjustments on a weak tube to get it looking as good as possible. Given the construction of the cathodes (guns) in that crt, only a very low level crt reactivate should be tried on it. The hard rejuv most crt testers give is highly likley to completely destroy the cathode on that crt.

Distorted Color and geometry of Picture


I've posted this solution several times but here goes. Try setting up the convergence through the menu by accessing the convergence setup menu. If this fails to work you have a bad digital convergence box and need a tech to replace it. About $60 to $100 fix.
