I thought I'd post this in here as well, hopefully you can help

Hey guys, weird question for you. What kind of electrical issue would cause a projector to not be able to display at 60hz, and only at 70hz? There are 2 projectors ceiling mounted in 2 side by side rooms, they will only run at 70hz, but if you change outlets by running a cord directly to the 2 projectors they will run at 60hz. The only thing I can think of, and I may be completely wrong, is that the power cord in the ceiling is either defective, or running into interference...maybe...??

Opinions? :confused:

Try replace the cord. Also, make sure to use a cord that's higher in gauge. Most projectors cords are of higher guage (thicker).

Actually lower gauge is thicker. Well at least for car audio :)

Also I wouldnt have a power cord in the ceiling. Thats a fire hazard.
