I was called out to check this huge juke box after a engineer sparked the main power supply board in front of the owner and left it humming and not much else!
He left red faced and a juke box sitting there for 3 months.
Mmm so let's get stuck in and power it up and all that could be heard was a very loud humming in the speakers, so a on wards and up wards...
My list of findings showed both amplifiers with shorted, fried reg circuit and popped filter caps and burnt feed resistors etc.
Some how even the jumper link plugs had been moved that operates the cd selection system..what the hell happened here???
The good news after many hours of sorting the blinking mess out and plenty of fff's and fully working juke box that filled the air with rich full sounding music.
