Just ran to a problem w/DH and not to good w/electronics.
Turn game on and there is a awful loud BZZZZZ/HUM through speakers. From what I’ve read it could be a blown amp chip on board...anybody know or have ideas? I looked at them and look ok but don’t know how to test if that’s what’s needed. Maybe I need to send board out for repair. Thanks in advance.

Thank you for the replies. I’m still looking into this and trying to diagnose.

Thank you cjchand. I checked and all screws are there and tight. I wish it was that easy! : )
