After an “max heat temp BED” error due to one yellow cable on the bed, my printer show wrong temperature on the display and i can’t do anithing about it, even if i unplug the thermisor the temp don’t drop to 0, i can heat the extrudor and the bed but after a short time the printer show error and i must restart it

i tried to reflash the frimware but nothing change, i clearly need your help pls

the bed and extruder are at ambiant température but it shows 65° and 74° (the temp moove 1 or 2 degre up and down it’s not frozen)

EDIT: disconected or not the temperature is the same, i guess the motherboard is coocked right ?

From what I can understand from your post…
You had a bed error from a wire coming off off the plate..??
Did you re-attach/solder the wire..??

Digging into the source code for the SV06 shows that it uses

A “type 1” bed sensor which converts to a

*  Analog Thermistors - 4.7kΩ pullup - Normal
 *  -------
 *     1 : 100kΩ  EPCOS - Best choice for EPCOS thermistors
 *   331 : 100kΩ  Same as #1, but 3.3V scaled for MEGA
 *   332 : 100kΩ  Same as #1, but 3.3V scaled for DUE
 *     2 : 200kΩ  ATC Semitec 204GT-2

Generic 100K thermisistor. The only source I could find for a complete kit is Direct from Prusa

They have several kits, find one with the wire length and motherboard connector closest to yours.

I’d try a new thermistor first.
