I received my Pironman 5 today and completed assembly no problem. Starting with a fresh download of the official OS, I followed all of the instructions to install the piroman5 service. Upon restarting, everything except the OLED display works (lights, fans, etc). Following the debuging instructions, I re-seated the OLED cable just to make sure. The software thinks it sees the display (i2c bus 1 address 0x3c): sudo i2cdetect -y 1 0 1 2 3 4 5 6 7 8 9 a b c d e f 00: – – – – – – – – 10: – – – – – – – – – – – – – – – – 20: – – – – – – – – – – – – – – – – 30: – – – – – – – – – – – – 3c – – – 40: – – – – – – – – – – – – – – – – 50: – – – – – – – – – – – – – – – – 60: – – – – – – – – – – – – – – – – 70: – – – – – – – – And the log (pm\_auto.pm\_auto.log) just shows: 24/06/06 17:01:04.389 [DEBUG] Initializing OLED 24/06/06 17:01:04.454 [DEBUG] OLED initialized 24/06/06 17:01:04.466 [DEBUG] WS2812 initialized 24/06/06 17:01:04.508 [INFO] PM Auto Start I’ve restarted the service, restarted the whole system, etc and it won’t go. Is there a command line I can use to try to manually test the display? I’ve tried using ssd1306\_bin from [GitHub - armlabs/ssd1306\_linux: SSD1306 oled I2C driver working in linux](https://github.com/armlabs/ssd1306_linux) and it seems to see the display and can initialize it, sent it text, etc but nothing shows up, Please advise thanks! ---

1.Could you please confirm if the OLED screen is properly and securely connected?Suggest unplugging and reconnecting the cables, then trying to start the pironman5 program again. 2.Could you please let me know what system you are currently using and the version of the system? This information will help us better reproduce and troubleshoot the issue. 3.When you access the PC-end dashboard, could you please share the log screenshots for the OLED screen with us? 4.Please try running the command sudo systemctl restart pironman5.service to restart the software and see how it worked.
