A1534 820-00244

Hi, i have an A1534 820-00244, that had liquid contact, and someone had submitted it to ultra-sound bath, but now it has no backlight.

In PPVOUT_S0_LCDBKLT (8500) I have 35V, and i can see an image on the LCD.

I don't have a known good lcd to test it.

Can you help? What should i check from here?

35V doesn't look too high, nor low.
But not sure the correct voltage there; compare with good machine.

Testing known good LCD assembly is the safest way...

Try another USB-C to HDMI adapter.
External USB device recognized?
