If you cant get it to sort it through other means, I recommend this aerial (with booster), which is very good you could try buying. What sort of signal levels it showing? as the booster alone should help! just search for the channels again once you plug it in.
DH has just bought a new Telly, an HD ready flat screen freeview job. But we can't get BBC 1 or 2 on it!! Or CBBC!
Any ideas? We could get these channels with our old freeview box. Do you think we need an aerial booster?
Is it just BBC1,2 and Cbbc - or every channel?
Digital will usually hold a picture better than analogue, until the signal is really, really weak. Unless you were watching analogue TV through a snowstorm, digital should be fine - your set-top box worked OK. So I wouldn't boost the signal as your first stage.
If just BBC channels are the problem, these all come off the same frequency. If it lists them, but doesn't show a picture, it may well be the signal level, which is usually displayed with the programme information. If it doesn't even list them, try a retune.
If it doesn't show any digital channels, then it can be about how videos, etc. are wired in. My first digital TV had this problem. In essence, the TV has two tuning stages - analogue then digital. I had to run the aerial into the TV first stage, run from this to the video and back into the TV 2nd stage. If you don't have a video, there is often a short cable to use that links the signal out of the first stage into the second. A set-top box only has one stage, hence no problem.
Can you get any of these, such as BBC News on channel 80? It should be all or nothing.
If you are in Coventry, you are using the Waltham transmitter (aerial points North East) or Sutton Coldfield (North West) Sutton Coldfield has a powerful analogue signal, but middling on digital and some blank spots around Coventry.
What to try (in order of severity) -
Some video recorders interfere with digital signals of a close frequency. MUX1 is channel 41 on Sutton Coldfield and Ch49 on Waltham. Try disconnecting the recorder from the TV.
The Sutton Coldfield transmitter has various channel problems with reception and channel numbering. Some people have reported MUX1 channels turning up in the channel 800-817 range. Do a 'hard' reset. Unplug the aerial and rescan. You will get nothing. Put the aerial back in and scan again to get a channel listing.
If the old box works & the new telly doesn't, perhaps there's something wrong with the new telly? Worth going back to the shop to complain. After all, wouldn't want to miss The Secret Show, would you? :o)
Well, dh bought it off ebuyer.com. I have since read reviews of this tv and to be honest it DOES sound like the appliance is useless. However, getting my husband to admit he's bought a wrong 'un is easier said than done and I reckon I'm destined to have this particular monstrosity in the lounge for some time (was I talking about the tv or the husband there?)
