Hello,
I bought the TH280 V2 Ultra AIO and the LCD Panel Kit. After hooking everything up both displays turned on and showed up the gray TT logo as soon as I flipped the power supply switch on. After booting up the PC (Windows 11) the panel LCD blinked around 3 - 4 times and then if went off completely, I could hear the windows sound when new hardware is discovered every time. I then launched RBG Plus v2.1.6 and under lightning I can see the Ultra LCD but not the Panel LCD, since then I've tried unplugging the AIO display and just hooking up the panel LCD to a different 9-pin USB port, running RGB Plus in debug mode, using a different cable, but the display hasn't turned on once since. It does show up in device manager as a "HID-compliant vendor-defined device", "HID\VID_2516&PID_0157\6&17A4BB9D&2&0000".
I sent out a support request to Thermaltake, but in the meantime I'm hoping someone out there might know a solution,
Thanks.
