Be warned : many things here have to do with electronics, and also with electricity. You MUST know what you are doing in terms of security and personal safety while handling such things, and take all the required precautions before you try to fix or even just open something that might be dangerous and potentially lethal. Please be careful, if you’re not sure about how to do it , don’t do it. The responsibility is ultimately up to you.
