HotEnd temperatrure

Hi
I changed the thermistor to hotendu for NTC 3950, everything worked well, but now shows me the temperature hotend 98°C even if it is not warm. This temperature is shown even when the sensor connector is disconnected. I use today B477 FW Vert MArlin 2.0x. I tried even the original FW 1.1.8 from Geeetech and the error is still showing. I'm sorry about English.

The temperature of 98°C is shown even when the thermistor is disconnected (formerly -14°C). I did a deletion of the M502 memory but without effect.
Fw MArlin V2.0 from VERT works excellently has a lot of extra features.
Thanks

I'll have to check the cabling to the board, the thermistor when hotend is heating works, only the lowest temperature is 98°C.

Hi VERT,
Apparently, the thermistor on the board was damaged. I found a damaged cable with a voltage for Hotend, which apparently touched the pcb where all the connectors from Hotend lead. I know that the printer showed me a temperature error several times and apparently the input on the board was damaged. Would it be possible to transfer the damaged input to other inputs and show where to edit fw? The entrance works, but probably not quite well.
FW I use your version of MArlin 2 build 477 setting 4 steps so the table will be fine.

Thank you Ales

Is there really no option to plug the entry elsewhere?
Motherboard I have gt2560 v3.1
