With all due respect, if you don't know where to start looking, then
please don't.
Unless you really know what you're doing, then you should not remove the
lid. Fault finding could easily result in the need to power up and
expose yourself to many hidden dangers.
It's been suggested that lack of AC power may be the cause. That should
be a safe thing to check, without opening the KPA500.
Stay safe - send it back to Elecraft. :-)

Subject: [Elecraft] KPA500 Dead
I was operating on FT8 20 meters for quite a long time with my KPA500 running
about 400 watts and heard a few pops (like something arching). Heard it a few
more times then the amp went off.
Now it will not power on. No lights, nothing. I checked the fuse and it is OK.
Can you tell me where to start looking?
Thanks
