Re: I replaced a network cable. -> We replaced a power cable
Ive just experienced a similar but different problem. We were in a drama competition, where groups put on a play, and an adjudicator gives marks for presentation, acting, technical etc.
We had a play and a critical part was projection on to the back of the stage. The projection worked the day before.
When we tried it with out play, we found someone had hung a black cloth in the auditorium - blocking the projection.
Our lighting man got his own projector, plugged it in to the mains, and computer and it would display the set up screen, but not talk to the computer. He tried everything. He finally used a different extension lead thinking it will make no difference, and it suddenly worked.
The problem was that the computer and projector needed about 5 second to sync up. The extension lead had a dicky plug and would drop power for a millisecond, every second or so. As a result, it never synced up
This took him 60 minutes to find - all the time we were allocated to set up the technical stuff.
Biting the hand that feeds IT
