I have an LG42LD790 TV which has all been working with no problems. Earlier this evening the screen went black and came up with "no input". The inputs being used come up on the screen but when any are selected it comes up with "no signal" message. Not had this ever before. Have switched off and removed all connections and left for 15 minutes and reconnected everything but still same problem. Please help as have two sons who are most annoyed

Did you pull the power plug when you disconnected all the connections?
That is supposedly the process to reset the main board. Hopefully the main board doesn't need replacing. (Sorry for the separate posts, I can't figure out how to edit the comments.)
Have tried it and still no luck. TV did make a quiet "swoosh" sound up and down and then showed no signal again. Thanks for the suggestion but will need to call someone out to sort
