Yea, I have been dealing with Infocus products, since these dumb bunnies
in the school system
don't know what they are buying. I have to send out all
InFocus-Proxima, that I cannot repair.
They won't sell you parts or manuals. Like so many other factory
service facilities, they have
a flat fee. Sometimes you win, sometimes you lose. But what choices do
you have. There are a
few Infocus/Proxima ASC's. But your repair cost may be higher than the
Factory's. Plus they
usually have a higher estimate fee. $150.00 typical. Go to
Infocus.com. They do seem to be getting better in customer relations.

As far as I know Infocus has an exclusive service
contract with U.P.S. NO parts or info available.
YEP! Brown is now our competator.
As is I.B.M.
