    820-00165 Missing BKL_PWM

    I've got an 820-00165 here that came in with no backlight, working perfectly apart from that (image is fine). Only visible corrosion I could see was a tiny amount around U5110 which I cleaned up, it seemed entirely cosmetic. D7701 - 8.6v both sides XW7720 - 8.6v and clean BKL_EN - 2.83v...

    820-3476 with short on ppbus_g3h

    I've got a 820-3476 which is only showing 1v on PPBUS_G3H and about 300 ohms to ground. There was corrosion around R1410 and R1617 which I've cleaned up and repaired during my first pass over the board, but apart from that it's clean with no other visible issues. Pulled F7140 and showing 12.7v...
