I need help with my GS800. As the projector heats up while running a film it starts to make a loud squeaking noise, I know its coming from the front and have checked the rollers but I can't find where it's coming from, anybody else had this problem?

It's possible that you need to lubricate something in the front arm, or there is some other bushing that is starved for oil. If you haven't cleaned and serviced it in some time (or ever), I would look it over and lubricate all moving parts with an appropriate non-gumming oil.

the safest bet for cleaning off old oil is likely to use some sort of petroleum product made of strait chained alkanes, like heptane or low oder mineral spirits. These tend to be less harmful to plastics than things like acetone, and MEK.
