Looking after a neighbour’s house while they’re away and trying to work out how the TV works 
It’s an LG TV with 3 remotes:
- One to work the TV
- One for Now TV
- One that doesn’t seem to be for anything in particular (see pic of non-LG one - I can’t work out what it’s for exactly).
The neighbour had explained each remote to me and how to switch on the TV before going away buuut the TV’s not working very well and I don’t really want to bother them so please could I ask you lovely lot to help me?
When I switch on the TV with the LG remote, it comes on but says ‘no signal’ on the screen.
The Now TV remote works fine but I can’t work out how to use the TV with the other 2 remotes.
I think I have to change the HMDI on the main TV but I’ve tried that and it’s still not working :/
Thanks in advance for your help!
