I have an LG tv and I was just watching it when it flashed up 'no signal' all other tvs are working in the house except this one please help.
The TV will flash this "No Signal" when it does not see a live signal at the selected input of your TV.
It sounds like the signal at the TV's input is not good to the TV, or the main board in the TV is having a problem and processing the signals correctly.
Try selecting a different woring device connected to the TV's input like HDMI1, Component1, or ..... to see if other inputs are working on the TV.
Good Luck.
