How to repair amplifier no sound?

[@alfaman4113]

Would have been nice if you could have explained what you were doing or trying to do

Hello, I have 5.1 surround sound system here is the problem Couple of months ago it stopped working, as in it doesn't amplify the input sound to the speakers. But just yesterday, accidentally I plugged it to 110v source(normal 220v) and it worked, of course there is a buzz sound coming out it(I guess that's because of low power), on 220v it's still not working. What could possibly have gone wrong?

Video is not just for you ahole. Noone cares it was only a dry joint. Point is he found issue and fixed it. Try to make yourself look smart but it actually shows how dumb you really are. An annoying know it all that noone likes. Great video thank you uploader.
