The board has gotten wet, you can see it in the pictures. The display stays dark! No backlight. I think I have to bypass the front of the needle point too? Unfortunately I don't have a board view for my A2338! Is there a chip in the picture for the backlight?

by bigbadbiosHi,
I am trying to fix this liquid damaged 2020 Macbook pro and I noticed something weird.
When I push on/around the renesas 501cr0b IC, which appears to be a clock generator/ multiplier, If I apply lot of pressure, the device will reach 19.9 volts and seems to be trying to work.
I have thoroughly reflowed that area and completely removed that chip (there was some liquid stain in that area) but no help. I have just 5v 0a unless I apply the pressure.
Your help is GREATLY appreciated. Thanks! -
by dbuergiHi all,
i have a A2338 with water damage on the logic board. Cleaning it showed some heavier corrosion around U7000 and surrounding caps. Some are totally broke.
I get 5,2v when using both USB-C Ports but until now i didn't make any more tests.
Since i'm a beginner i want to know next possible steps. I'm not afraid replacing the intersil 9240hi but the other parts with 1mm or 2mm scare me and i don't know where to get replacements.
I fixed other laptops but this ist my first apple device ....1 Photo -

Macbook AIR Model A1466 Diagnostic 09-01-2021
Issue: Liquid damaged (beer spill) Macbook AIR will not power up.
Problems & Resolutions
1) Attached Apple magsafe power adapter. No green / no orange light. This confirms the absence of the PP3V42_G3H voltage rail. The PP3V42_G3H rail is the primary voltage rail necessary to communicate with the magsafe power adapter to report the green or orange light status to the end user....09-01-2021, 09:31 AM -
by classicandyHi Everyone,
Please, I have a MacBook Pro A2338 M2, board number : 820-02773. The speakers and the microphone of the Mac are not working and I need assistance in fixing.
UR730 got damaged and short-circuited the motherboard. After removing the shortened IC; before and after putting the new one I ordered, the speakers [specifically the other one not affected by this IC] and the microphone are still not working. I do have sound through a Bluetooth speaker device or when I connect a headphone with microphone to the jack 3.5mm input. Also, media files do not play unless a... - Loading...
