Integrated stopped working


In 20 years of hifi, I’ve really never had issues.  Until today.  I’ve been using a Micromega M100 for almost a year.  Today, it won’t turn on.  Nothing has changed between today and yesterday.  Just won’t turn on.  Checked the fuse, it’s good.  Checked my power source, it’s good.  There is no hard turn off.  Just the standby button.  Any thoughts?

Guys, thanks for all the responses.  As many have suggested, I’m gonna pull the fuse and test it.

regarding the power cord, I unplugged and replugged many times with no luck.  I have two other devices on this same receptacle, so I know I have power at the wall.  It would be strange to me that almost a year into the integrated and without it be moved at all, the power cord would fail. 
My daughter unplugged the power strip all my devices are plugged into yesterday to reset the TV (which we do on a regular basis) and everything came back on except the amp - gotta be the fuse, right?  
I’ll pull it today to confirm.  Again, thanks for all the help.
wd40 into a switch? I hope that's the dielectric electronics cleaner your using and not the old school WD40 ah lubricant (cleaner really), that's not a dielectric and not good for electronics.
I checked the fuse with a multimeter tonight and it’s good.  So... I don’t really want to crack open the case, but it might be my only other option.
s7horton,

Use a different power cord and plug it directly into the wall. It it's still inoperative you have no choice but to open the case and visually try to determine if anything is amiss. I would focus on the power supply area. Good luck!

I'm assuming maybe incorrectly that you have the amp plugged into a power strip; since other devices are working did you disconnect the amp from the strip and plug it into the wall directly, or another recpetacle within the power strip that you know if working; maybe the issue is the power strip receptacle?

Just another thought
