Ender 5 fried

  • So I recently made the jackass decision to add buck converters to switch the stock fans to 2 noctuas, and wired them in reverse by accident like an amature.

    The screen no longer turns on, but when I turn the power on, the PSU fan turns on.

    Would It be safe to presume the PCB ( V4.2.7 ) is functioning? And if not, what would be the ideal board and screen combo to change to?
