Evening all could someone please help? I am trying to find a guide that shows how to tune the TV as it currently states channel 4. It there is no picture. I’ve looked on here (also YouTube ) to see if there is a guide but can’t seem to see one. Does anyone have a step guide that can show be what to do ? Thanks in advance

There is an auto tune button in one of the menus that should scan and re-tune for any available channels.

It can be pretty flaky though depending on how much signal you have where you live. When I bought my L322 i also found no channels regardless of where I tried tuning it, so I ended up swapping out the entire TV module in the rear and ever since then ithas worked beautifully (where there's signal).
