Hello, I have just got a topfield 5810, and I appear to be having some problems. After tuning the set I noticed that I have two of every channel. In all cases one of them does not work. On BBC1 & 2 the second entry does not work and I get the message "no signal at tuner 2", on ITV and channel 4 the first entry does not work and I get the message "service is not running or scrambled". Added to that, if I go onto the working channel 4 entry, I see a picture for about 7 seconds and then the screen goes black and no sound. I got this cheap from superfi because there was a dent on the backplate. Looking at it though, the RF loop 1 out coax socket was also bent over a bit. I have installed the coax patch cable from RF loop 1 out and ANT 2 in. Apart from this, it appears to be working ok. Any suggestions as to what the problem may be? Thanks, Nick.
