Im a TV tech and the amount of customers that have said " It might just be a fuse" to me over the years I could'nt count. And I still hear " might be a valve or something"
If Ford Fairlane ever sells his Pro Foot Ball he could say " It may be just a fuse or something simple"
Bloke gave me a TV to look at, adamant it was the fuse.
Unbelievably it was! Been running for six months.
One of those rare quick fixes.
