there is no sound output on the speakers anymore
I dont understand much of the internals of my technical devices, unfortunately. Its getting power and I can turn it on, LED's are shining from inside and from the power button. Also you can connect other devices t the AC-Power Outlet. But there is no sound output on the speakers anymore. I tried every input channel, different cables and every output speaker channel. All dead output.
And diffrent speakers of course
Im affraid I damaged it when I, in my stupidity, coneccted a battery powered fary lights to the music output (speakers) adapter/ports. I know, I shouldnt have done that. But im not sure its realy the reasen for it to be dead and I never would understand whats damaged exactely.
Thanks for your interest! Havent expected that :)
PS: I also checked the boards inside for any burned stuff. But with my untrained eyes I coulnd find any obvious damaged components

ok I got the multimeter now and watched some youtube videos to get an expert.
I would set it like on the photo to measure the 2.2V:
But then… Where do I have to touch the black and red stick of the multimeter? One of them to the 7th pin of CI 401 (photo), but which one? And the second to…?
And I’ll do all this while the amplifire is pluged in and powered on right? Little afraid of that :)
Questa è una buona domanda?
