0Learn Electronics Repair #22
The paying jobs just keep on turning up. This one I thought would be really simple to repair, just like fixing Christmas Lights - but in the end it turned out to be rather more interesting than that! I hope you enjoy this short video, and hopefully someone can explain why I was seeing some very strange (seemingly impossible) voltages. Post your answers in the comments below :-)
