Lg Tv Lost Channels Incl Itv

[auntie-bertie]

We usually watch through our Sky box so I'm not sure when this happened but just turned on the TV (Sky box is off) and just started flicking through BBC1..BBC2..then straight up to Ch9 BBC4. Then another huge leap to Ch16 QVC.
Have retuned several times but no joy!
TIA
ps: all channels there via Sky box

Missing channels are a classic symptom of poor signal strength. [NB: The strength and quality of the signals arriving at your aerial don't remain constant. They're affected by lots of factors, including things like the high atmospheric pressure we're currently encountering, which can make it easier for interference from other TV regions (or from abroad) to occur. So getting adequate signal strength on one day doesn't mean that you'll always get it on other days].

The first thing to do is to take a look at your TV aerial and check that there's no obvious problem with it. (I offered that same advice to someone on AB once and they came back to say that they'd found their TV aerial lying on the ground in their back garden! You might find that the storms we had earlier in the year have knocked your aerial out of alignment).

Then check that any plugs and connections in the aerial's lead are all secure. (Simply not having the aerial plug pushed firmly enough into the TV's socket can cause problems).

If that doesn't help, simply wait for a day or two to see if the problem clears itself. (High pressure problems yesterday meant that the normally strong signal I get on my radio from Classic FM suddenly disappeared under much stronger interference from a Belgian station. When similar interference problems occur with Freeview signals you tend not to see or hear the interfering stations but you simply lose channels instead. So your problem might disappear - possibly after another retune - if you simply wait a while).

If things still don't improve, install a signal booster

Thanks. I called LG and they blamed the weather. Wrong sort of sun I guess.....

At least it proves that I wasn't spouting rubbish when I suggested that high atmospheric pressure might be a partial cause of your problem!

However it also indicates that there's a deeper cause, in that you're only getting a fairly weak signal to start with. (i.e. your aerial and TV can cope on most days but things tend to go wrong when there's high pressure about - you'll probably also experience problems if there's heavy snow).

So my advice to install a signal booster (and then carry out a further retune, ensuring that you choose the option to 'scan from new' - rather than 'adding channels' - if appropriate) still holds true. That should mean that you'll either eliminate your problems or, at least, experience them far less frequently.
