820-01521 burned L8570, not waking up after closing the display lid

[George_RL]

Hi,

trying to repair this board for my customer. everything else seems fine on this board.
After closing the display, Backlight doesnt show up but lcd is working.
L8570 is burned, dont know which part on other boards i could use to replace it. have a few a1502 a1398 a1466 a1706 faulty boards for parts.

Hope you can help me

First of all, welcome to the forum!

L8570 usually gets burnt because of short in the flex inside LCD assembly.
You should try another one.
What is actual PPVOUT_S0_LCDBKLT voltage?
