Poor service on Freeview but only on ITV and Channel 4 - any ideas?

[Trickytricky]

The reception on our freeview is really rubbish BUT it's only rubbish on the ITV channels and all the Channel 4 channels. Anyone know why this would be? I've been onto the Freeview checker and apparently we have good service in our area. I don't think it can be an issue with the aerial as surely all the channels would be rubbish if it was?

Can anyone help?

Bump

I had a message on my TV last night saying (paraphrasing) 'you may need to rescan your TV or set-top box to keep viewing itv' I can't remember what the reason was- emmer dale was on so I just pressed yellow to hide the message

Thanks SilentBob - I have tried to retune but that doesn't seem to work either. Pathetic I know but I need to work out a solution before Downtown starts or Sunday evenings could be ruined.

I have similar problems except that mine has become gradually worse, first it was the bbc channels that i couldnt watch now its pretty much all of them and im lucky if i can pick up one or two channels. i have no idea what the problems is and im fed up with it to the point that i no longer bother putting the tv on which is annoying as ive not had it that long. im considering just cancelling the tv licence and watching catch up on the internet but i keep hoping for a miracle before i make the phone call to the licensing people!

Its our bbc and itv dh has retuned it twice the stuttering is driving me daft i like watching tv in bed

We returned about 3/4 Times then unplugged it all and plugged it all back in, it's been working fine for.a.few months now

Cunfuddled - can I check what you plugged?! Do you mean just unplugging the aerial from the back of the TV and the wall or something else? Thanks.

Literally everything

You need one of these

I have one of those filters but it hasn't helped with my reception at all.

Could it be signal overlap? We live on the fringes of two transmitter areas and the tv my kitchen got really poor or no reception on one or two of the digital channel 'groupings'. I ended up having to manually retune them to recieve the signal from the 'other' transmitter. All the other TVs in the house were fine.

I got all the info I needed here, I'm no techie, but I managed to do it with relatively little fuss!

Funny, we have satellite and ITV has been rubbish for the last few weeks. Unwatchable at times. DH was going to replace the aerial cable but I can't understand why it's not attracting every channel.
