I have a Greyhawk Electriscreen. Tonight when I fired up the projector the screen drive squealed and slowly started the screen down. I quickly pulled the 12V trigger cable from the screen control which reversed it. The screen retracted normally. Since it went up normally I tried running it down again. This went normal also. I ran it up and down several more times without incident. Does anyone have any ideas on what this might be?
