Been trying miserably to diagnose this problem and learn about the the capacitors. So, I have a Yamaha rx-596 AV receiver. For years it has run perfectly. Got back from a trip and it won't power on. Read that it is usually the capacitor running out of juice on the power board. I will provide picture of this area to see if anyone knows better, but will also ask a couple specific problems beyond the obvious, how can I get the power back.
The couple capacitors located on the power board:
I understand the nanofarad readings (This one is 103, meaning 10 nanos). What is meaning of the difference between J and K lettering as in "tolerance" +-5% vs +-10%? Is interchanging these ok or harmful?
How do I figure out the voltage on these when they are not listed on the piece? What voltage is ok for the ones on the power? The only ones available online range around 400-650.
What is the meaning of M85 on the capacitor? What does this indicate?
I am asking these questions to figure out a safe replacement for these to troubleshoot the power issue. I am willing to solder and desolder to figure it out. If you know any answers, or even better, know what I am doing wrong in my approach, please help. This is my baby, had it for almost a decade and it's a beaut. It is simply not powering on. No clicks, nothing, no response from the on/off button.
