I have a Labgear remote powered distribution box which I've had about 4 years. However, I am already on to my 3rd PSU and that one I believe is on it's way out.
My set up is as follows:
1 TV aerial mounted on side of house externally (upgraded since buying amplifier) we are in a poor signal area due to trees blocking route to Crystal Palace transmitter) in to labgear box.
1 FM Radio loft mounted and connected to UHF port.
1 cable from labgear box to PSU (and back!)
1 fly from PSU to set-top box (YouView)
1 fly from YouView to TV, with the RF Port through enabled on YouView Box
1 cable from labgear to bedroom (PF100), into You view box
1 fly lead from youview box to TV (as above)
1 older cable from labgear to radio unit in lounge.
I phoned labgear technical to ask why I was losing so many PSUs. They told me that I must have a "leak" on my system that was causing it to leak power. He advised me to check everything for loose connections etc.
I asked if the buzzing would stop if I fixed it - he said he thought it might!
So I stripped everything out, so it was just the TV aerial, down to the PSU and nothing connected to TV. Still buzzing! I'm pretty sure all the connections on that were good. I have used screw on F-connectors throughout the installation.
Does the labgear guy's explanation sound reasonable? (I dont know what causes transformers to go buzzy!) or is he trying to palm off the problem due to an unreliable product?
How can I go about looking for leaks? Any kind of tester?
