Topic: need help DaVinci 1.0 no errors but also not working

Hi, I got this printer 2nd hand and it seems that there is something wrong with it:
In the present state I haven't loaded a spool of material as I want to test all the moving functions first.

From the front button menu I go into utilities, unloading filament --> message wait heating up, 10 degrees C.
In fact the temperature displayed it too low, the extruder is not heating at all nor is the fan running.
There is no voltage on the PCB outputs to the extruder heater (the heater has 7 ohm resistance and should be ok).

Now what condition do I need to see the extruder heating up (do I need to load a filament spool first) ?
Why is the temp too low ?

If I use the JOG option under utility I can drive all the axes with the push buttons except the -Z for the table to go upwards.
The table is easy to move by hand (no mech. issues) and the optical end switch is working (I measured it) so there must be something else preventing the movement.
I believe the motor and driver for the Z axis are OK, I changed the driver IC and had the same behavioral afterwards.
The software and firmware are up to date according to the notebook connected.
Could there be still an issue with the software in the SD card ?

What is the actual temperature in the location where the printer is? If it is actually 10c then it needs to warmer. There is a minimum temp the printer will work at of like 22c.
