Issue: 6 red blinking lights on display. Troubleshooting: Have opend up and bypassed the BL_Error connector to ground. This has not solved it. I can see one bank of LEDs do not power up. I have confirmed the LEDs are fine by powering them locally so it seems to be an LED driver / OUTOPUT error on the powerboard APS-384 147460911 Looking for advice on what I can replace to get this working again without replacing the whole power board.
