[Elecraft] K2 Troubleshooting help

[Sam Smith]

Got this K2/10 used. It has been working great, made maybe 50 CW QSOs on it.

Then it got stuck in transmit. I was using a straight key at the time. Shut it off to stop it.

At first I thought I had set the menu wrong, since I swap back and forth with a paddle. Then I discovered I cannot get into the menu anymore. All the other buttons and knobs work fine. The display works normally. Only the menu button doesn't work.

So I checked all the voltages - looks fine. I disassembled and checked the switch with a meter - works fine.

Any pointers at what else I can check would be much appreciated!
