Hello.
This macbook came in like 1 year ago because of distorted image on the screen, in that time I resolder U8900 and reballed the GPU.
The computer worked fine for that period of time and now it is randomly crashing: black screen followed by a restart. It says "panic (CPU...")
Ive red...
PP1v35_S3_MEM: 1.38V
PP0v75_S3_MEM_VREFDQ_A: 0.698V
PP0v75_S3_MEM_VREFDQ_B: 0.700V
4 retainers of the heatsink are fine. No damage around retainers either.
Thanks

I have PP5V_SW_LCD shorted to ground when connecting the screen (0 ohms)
When screen disconnected I got 58ohms to ground or 0.064V (diode mode)
-Any recommendation on the screen?
-The 0.064V sounds good?
Couldnt find any different measurement on the chips.
I replaced UF400 and the machine taking 20V y both ports.
Now, when connecting the screen I only get 5V on both ports. If I disconnect the screen I can hear it chimes.

Replaced U5700 and the board takes now 20V 0.200A when connected to UF500.
When connected to UF400 only 5V and the USB-C meter restarts.
Any idea? Thanks!
Just wanted to mark this one as solved.
Replaced the display and the machine is wotking fine.
About the HDMI, it seems that my external monitor decided to die. External video is working.
Is there a way to identify an original screen for a a1708 emc 3164 (or any model) from the seller ?
Any reliable shop in the US?
I have seen some in Amazon and in aliexpress, but I think they are copies.
Thanks!
