I got a new telly about a month ago and put my perfectly working old one in the shed. Tonight my son is having his mates over to sleep in the shed and they want to watch some old videos but the telly wont go on. No life whatsoever. Could this just be damp? Will it some on later when it's dried out? I've got the gas heater on at the minute AND I've changed the fuse etc. Anyone have a clue?
