I need some help - my TS80 shows 130-140 C lower temperature, than actual one. I read all the debug menu values, all seems OK, checked D25 tip (4.45 Ohm, seems to be in range), done reset and calibration few times already, changed firmwares. etc.
Looks like it is a hardware problem, temp sensor chip probably. I can do reflow of the board (also probably I can request change for iron from the seller), but:
- I do not know whether chips are sensitive on temperature (afraid to burn out)
- which one to reflow
- whether it could be possible to return TS80 after that and whether it will fix the issue.
Any advice?)))
