i got a macbook pro 13 inch with touch bar A1706 2017. it stopped after liquid damged J4402 and J3300 was a liquid J4402 burned and i removed the connector and cleaned motherboard . Now i am using JB500 to connect charger and the motherboard turns on but no display and no caps lock react. I...

I was comparing j8500 of both schematics(820-01958-820-01521) where I tested the LCDs,J8500 same all points even ALS same .

Where to buy original parts ?

i tested other 2018 same result

I put the old LCD on and to my surprise the keyboard light came on. the broken lcd belongs to core i5 2020 not M1 the good lcd is 2018

i Will connect original broken lcd and connect to external monitor and test. O don’t have other working board to test

No new lcd I took from other laptop The original is broken

Both lines has 425 ohms

R8556/58 has continuity with J8500

The resistors are good No shorted to the ground

You meant R8556/58

No members to help this?

I can’t check traces because I don’t have other motherboard to copy. Do you have one to help see continuity with multimeter?
