Projector In One Of Our Rooms Is Picking Up A 'Hum'
One of our LCD projectors is displaying an image which is impossible to look at after just a few minutes.
There is a pulsing which moves down the screen. This is reproduced on the PC monitor. We have swapped the PC, the screen, all cables and the projector [The cable run to the projector is still in place]
We have checked the room for a bad earth and eliminated that as a potential cause.
We are now wondering if it is possible to get a Ground Loop Isolator [for video] Does such a thing exist? Where would I get one?
What are other options that we have not thought of?
