Hi all, A friend just received a thunderbolt from an ebay seller today and asked me to check it and wire a quick power supply for him. I used a switching power supply, pc-like, just for testing and tried both lady heather and tboltmon. I wired the power lines as the TVB web page, but connected only one GND line as the connector supplied didn't have enough wires. The unit completes the self-survey and has all outputs (10 MHz and PPS), however, the temperature starts at -0 C at power on and in a few seconds settles to -1.249 C and never moves again. Also eeprom contents is invalid at each power on and no setting appears to survive after power off (not even the saved position). Does anyone know if there's a simple explanation for this or a possible common fault for eeprom and temperature or both eeprom and termometer chip are probably bad? I suggested the friend to ask for a refund anyway as my own thunderbolt works fine with default settings.
