I have a BK Precision 8540 DC load and the front panel controls don't seem to be working.
The front dial doesn't change any values and most of the buttons don't seem to work.
I haven't dove too deep into it yet, but have measured 5v on the front panel and looked for the obvious issues such as broken wires, connectors, and solder joints.
Has anyone seen such an issue and been able to fix it?
