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"
Yep used to hear similar or my favourite of all-time when you know the person doesn't want to pay........It'll only take you 5 minutes to fix. Well if its that simple fix it yourself!!! I got this usually from neighbours and I'd spend hours on their PC rebuilding the system from mega viruses and deleted system files.
