Last night I tried baking the mother board on my 42" LG Ltd TV as it would only display 'no signal' to all hdmi sockets. 10min

Did you try other signal sources?

Did you try other known working HDMI cables?

Did you try new batteries in the remote control?

Are you able to download a phone app that will allow your phone to act as a "remote"?
