I am working on an friends K3 (#4446), recently purchased used. When I got it, Power-On resulted in "ERR DSE." Firmware load failed, so I did EEINIT, and then the firmware (4.22) loaded correctly. After going through filter setups to match the on-board filters, things seemed to be working correctly. But then I tried to increase power beyond 12w, and now I get the "ERR 12V", which my friend had seen before. When that error occurs, the KPA3 fans come on. The manual says to reset the circuit breaker, but it wasn't tripped. Just for kicks, I tried to do the Tx Gain Calibration through the K3 Utility (dummy load attached), and even at the 5w level, it fails.
I need some advice on how to proceed.
