Hi, Paul. I had the same problem a few years back. Unless you can see a carbon trace somewhere, it's likely to be the diodes or the microprocessor. I replaced the microprocessor purchased from Elecraft and that fixed it. You may want to try snipping and replacing the diodes, first. I purchased two microprocessors just in case it ever happened again: my K2 is the QRP radio for the station with connection to logging software. The K3 was untouched.
As I recall, the lightning strike took out the uVerse modem and a board in my PC. After that, I changed to using WiFi for the PC instead of a cable just to eliminate one path for future lightning strokes.
