First thing I'd suggest is to clear the DC/MMI clear and then re-enter the door settings and factory PASCAL settings.
It sounds like either a DC issue or the HVT gone bad.
If you clear the DC and the issue resolves for a short time and then reappears...replace the DC pcb.
The reason to suspect the DC is the fact that the reference values have gone back to 0...and that's why the SGNL levels are reading 0.
Looks like the information that was stored on the DC for the machine to compare against is gone.
The SGNL readings can be anything....as this is just reading the density of the dev at the time...but the reference values MUST be present for this to happen and they just aren't there.
