Bought a LG 47LD450 a few months back and tried to tune in the freeview stations (using one of these standard connectors) only to find that it would not pick up most of them. This includes Ch1-5, all other BBC/ITV stations, etc. We get Dave, a couple of other pointless channels and one or two radio stations and that's it. We're stuck using a cheap digibox that's connected to the TV via SCART that picks up every channel no bother, just wonder if anyone knows what the problem might be with the TV and how to sort it? Cheers.

Sounds like your signal may be a bit marginal. It is not unknown for different bits of kit to have different tuner sensitivities. If the box you are using a bit more sensitive than the telly then it might be better able to use a weak signal.

Trouble with digital is that it works perfectly as the signal decreases then starts to break up a bit and suddenly stops working altogether.

If that is a picture of your actual installation then are you using the same cable with the box? Is it one you made yourself or a bought one? Either way it looks to have standard Belling Lee type plugs on it. So take the plug apart and double check the wiring. Make sure there are no stray strands of screen braid floating about that could potentially touch the inner conductor. That would do the signal no good.

Similarly check out the wiring to the socket. Again check for stray strands of screen braid and check all the connections are tight and neat.

Also see if the box and TV have a signal strength indicator. See what level it is showing. If very low then perhaps a simple booster amp will solve the problem?

The other situation is too high a signal oddly.

Sounds counter-intuitive but having too much signal can be a problem as well. If the tuner is overloaded then it can generate all sorts of nasties that can affect reception. Perhaps the services you can receive are on lower powered multiplexes? In that case a simple attenuator plug in line with the aerial could sort it out. Places like Maplin sell them.
