Have a Samsung TV UE55MU7070. In the UK and just plugged into Freeview. Only problem is some channels have bad reception and pixilated pictures. The signal strength is 100% on these channels and 0% signal quality.
I know the aerial/cable are not at fault as I tried a different TV with no issues.
Tried resetting, unplugging, retuning and a number of different suggestions found on the Internet to no avail.
We haven't tried that yet, mostly because we have another TV that we tried on the same aerial and it works fine. We only started having a problem when we plugged the Samsung in.
Weirdly sometimes it looses reception on the only channels we can get (BBC channels) but if I flick the channel up and down one it fixes it
@fluentz: For the affected channels, please try heading to Home > Settings > Broadcasting > Expert Settings > Manual Tuning, and follow the on screen prompts. If the issue persists, please head to Settings > Support > Device Care > Self Diagnosis > Signal Information. Here you can use the signal strength information to adjust the antenna for increased signal strength and improved HD channel reception.
