Red power LED without any other LEDs usually indicates a power issue with incoming power or with the projectors circuit power supply. You should try a different power source first.
Turn the brightness up slightly and turn the contrast on the highest setting. There may also be settings to control wether your projectin on a wall or on a screen. Make sure these settings are correct to your setup.
I'm looking at the specs for yu projector right now.
Native resolution = 800 x 600
Maximum resolution = 1280 x 1024
The problem you describe can occur when you run a hi-res signal over 1280- x 1024 into your Dukane projector.
You say that this problem is there, whether projecting a computer image or not.
I have two thoughts.
(1) You have suffered one or more LCD panel failures.
(2) The combining prism in your optical block has come loose.
In either case, there is no simple repair that you can do yourself, and looking at the age & low-specs of the machine, don't put a single dime into repairing the machine.
if the focus motor does not work, the motor could be bad. or because it is an lcd projector, it could be the fly-eye lens or the light filter is singed and need replacing. also try matching resolution with source.
