We've got a rarely-used TV aerial point upstairs that doesn't work very well. The socket for the flylead was pretty loose so I fitted a new faceplate to see if that would help (only a couple of quid from Wickes). It didn't, but here's the weird thing. With the TV connected to the socket and the faceplate hanging loose I noticed that if I touched a screwdriver to the terminal that the centre wire of the co-ax cable goes to ... the signal improved hugely! Does that sound like the cable has a problem somewhere? It's not the end of the world as we only have an old (analog) TV/DVD unit up there for the kids to watch films on. But analog reception is OK on the aerial point downstairs, so I was just curious!
