I think he disappearedSounds like a broken mains lead if the light on the switch isn’t even coming on. Open the plug, unscrew the cord grip and pull on the live and neutral conductors. They shouldn’t stretch. If they do you have a broken one.
Open the casing and do the same with the mains lead where it enters the set. Cables rarely break in the middle as they get bent at the same point all the time at the plug and the panel grommet.
Hope you get it sorted easily.
