First rule of weird radio behavior – Do a FULL factory reset.Yes, and the second is, do a full disassembly
and reassemble the units.
Or at least a partial disassembly.
For example, pull the CPU unit and reseat again.
Just wiggle every plug and contact.
Don't pull the ribbon cables, just press them in a little.
They easily go broke.
Also remove and reseat the front panel after cleaning the contacts.
Don't forget to reseat the internal 5A fuse behind the front panel.
