IPOD HIFI dock/speaker constant buzz. where to find schematic?

[N4v4jo]

Hi all

I have an old IPOD HIFI dock-speaker. When I connect an Ipod in the dock or any audio signal in the AUX port I get a constant buzz. I'm trying to repair but I need the schematic. I have been searching for a couple of weeks already but I haven't found anything. Does anybody know where I could find it?.

Thank you in advance.

Schematics for an Apple product? Good luck with that.
Ask Louis Rossmann about getting anything from Apple for repairs.

With that being said I would check any coupling and decoupling caps. Specifically electrolytic capacitors concerning the power supply if the buzzing sound is at 120Hz. Check the dock connector for broken or deformed contacts.
