Hello, got a 00928 come in as water damaged but upon checking, liquid never hit the board. most on the LCD connector. nothing seems burned. diode reading on backlight output and MUX data pins are good.
right now macbook does not boot fully, no backlight or image either, using an external display i get the same black screen.
HOWEVER, I'm able to get to the startup manager by holding the option key, after selecting the drive i get no activity after this. This is on external display, nothing on recovery and nothing on diagnostic.
on the LCD i get nothing(known good LCD), i'm not getting EDP_BKLT_EN for backlight enable, i do have 5v and 3v3 going into the tcon.
i'm not sure if the no boot symptom is causing no display.
update** SMC bypass mode gives me low battery sign
