Home Theater Questions? Ask a Technician for Answers ASAP
Hi and welcome to JustAnswer,Thank you for the question and your patience. Should you still need assistance for information purposes only...Initially, have you tried gently tapping on the various buttons/selectors of the AVR-1612?
Bear with me as I review the repair/Service Manual for other possible user doable tries.
If the RESET was not corrective, then it would be indicative of an internal hardware issue.
Are you then considering a DIY (do-it-yourself) repair approach? If yes, do you have access to and familiar with a multi-meter and even a soldering iron?
Perhaps more importantly, would you be comfortable working on the inside circuitry? ...LIVE!
