Sony KD55x9005 - No signal, check antenna


Standard Member
In my quest to get away from overpriced cable tv providers, I got an aerial company round to make my Freeview reception as good as possible.
They checked it out and fitted a masthead amplifier and power supply.
When they left I was flicking between cable and aerial to compare picture quality when suddenly, black screen - No signal, check antenna connection. Nothing I could do could get it back. I also have a connection to an old Sky dish so I switched to that, ok for about a minute then same thing...No signal check connection.
Cable service through HDMI is still fine.
Seems too much of a coincidence right after having the amplifier fitted. Rescanning channels does nothing - no signal detected.
My question, if anyone knows, is it possible for the aerial amplifier power supply to blow the TV's tuner?
I contacted the company but so far no reply over the weekend.
