Hi there
This is definatelly a interference from a power cable. If any of your signal cables in the ceiling is closer that 5cm to one of those , you will get interference.
The Company that did the installation should know this and I would suggest you call them and tell them that they should sort it out. They should either move the cables or insulate them by means of conduit.

Sounds like one of those problems only cureable with expert knowledge of for example Chroma feed , Lcd function , lamp luminence, not to be a killjoy but it sounds like this is one for the engineers an estimate should be free and even if you dont have it fixed you'll know whats wrong if you want to do it yourself providing you have adequate training of course ....
