Hello, I recently purchased an Onkyo integra A8067 integrated amplifier from a garage sale.
I am looking for some direction of how to diagnose /troubleshoot the unit.
The unit powers up but it appears to be in protect mode. When the power button is pushed the unit will power up however I do not hear the relay clicking. There are red lights illuminating on some of the boards (see pictures). Not sure where to start. Thank you for any assistance.

Start by obtaining service manual. At least schematics. Hifiengine is problematic, but there are other web pages.
I would find out what voltages are before the relay. It does not click because there is likely dc on the amp output. Measure it. Then diagnose what is broken. Is is discrete outputs or chip amp?

Thank you for your input. Onkyo Integra A-8067 integrated amplifier uses a discrete output design.
