Yamaha HTR-2064 (2011) turned itself off, won't power back up (1 Viewer)

We've checked the fuse inside the plug and the fuse inside the AV receiver itself.

None of the capacitors appears to be damaged.

We've tried without any speaker cables being connected.

We can't perform a reset due to no power.

Any other ideas?

It could be a bad cap even if not obvious. Do you have a DMM (digital multi-meter)? I would start with testing continuity from the power supply and see if you lose it through any of the input caps.

Whilst selling it on eBay (as broken), someone messaged me and suggested I reset the main microprocessor by pressing and holding the Tone Control and Straight buttons whilst pressing the power button.

It actually slightly came to life! It made a 'buzz' sound, then click sound, and both only last for half a second in total before silence again. The display doesn't come on during this time.

I've let them know this and I'll await a response
