So nothing seems obviously wrong. I have an Arduino Nano with the correct picprog loaded to it, I plugged that into my STC, the Nano blinked green then the STC made the slight buzzy “I'm flashing” noise when I plugged in my Arduino. The green light on the nano board blinked fast for 2 min, then quit (standard as I recall) but when I unplugged the nano and put the STC on mains power, the LED still didn't turn on. I don’t know enough about Arduino to get them all hooked up together and “ping” the STC. Heck at this point I can't even get the Arduino Software to recognize the nano...
The "Orange box" is a transformer and , most likely, it's OK. Semiconductors failing much ahead usually. Could you make a picture of area near transformer?Much obliged Brumateur. Got a bit more info! I managed to power the PIC directly via an external 5v power supply and it lit up just fine. I bet the power supply is dead. I confirmed it's receiving 120v in, but as best I can tell (chemist, not electrician) it's only putting out 5v instead of 10. Anyone got a line on a replacement for that little orange box? Or a diagram of what to poke with a voltmeter to confirm my hypothesis?

The yellow arrows when grounded at the yellow circle are 5v DC. I'm pretty sure those are the other side of the transformer. The AC side of the transformer reads line voltage. ignore the red and blue wires, they run to nothing right now (was for an old project).
Between the arrow you must have AC voltage 6 o 7 volts at least.The yellow arrows when grounded at the yellow circle are 5v DC. I'm pretty sure those are the other side of the transformer.

Hey, have you been able to solve this? I'm in the exact same situation, and i dont know what else to try!Hi all,
Looking for some advice here on an STM8 board.
I have a new revision of the STM8 (XD-1000-V1.0) board that I can flash Emile666's firmware to just fine, but once flashed the temperature probe no longer works as it should instead it just counts up. I have four units and flashed two of them with the same results.
With both of the flashed units, a calibration with a 10.003ohm resistor results in the unit counting up from 25C until it hits 40C (about 20 minutes), it then oscilates between 40-42C indefinitely.
With one of the non-flashed units, the same resistor sits rock solid at 24.7 for over an hour without ever changing.
In troubleshooting, I have traced out the entire frontpanel (LCD) board and found it to match Emile666's exactly, despite the different IC package for the STM8. I have also traced the temperature probe to make sure the resistors were the same value on the backplane as Emil666's. Everything checks out.
Any ideas what would cause this?
My first thought is a floating input-- Do I need to have two probes attached?
Photos of the boards attached in case anyone is interested or has the same model.
