How to fix an lg tv that would turn on but there is only one channel working.
but before all the channels were working.
me .

In desperation, and with the clock ticking down to the must-see Reds v Crusaders game, I gambled on running the 'factory reset' function, then reinstalling all the channels.

Result: success!

Might be a useful tip for anyone else who finds themselves with this problem.

Cheers

Just try completely rebooting the television and then re downloading the channels again also reboot your cable box. If this doesn't work see if you can find a warranty on the T.V. and replace it. Hope this helps, have a nice day. :)

Ihad the same question but i tested it out and it didn't work.
