Hi,
This is my first post asking for help, but I feel I have now reached a point where I am out of my depth entirely.
820-01814-A board model, purchased with knowledge it was faulty and had water damage that had affected the touchbar. Water damage was located around the touchbar connectors to the point there were open circuits. When turned on the touchbar would light up, but the entirety of it was scrambled colours and pixelation.
I replaced the topcase (wasn't comfortable doing a touchbar swap) expecting this to be a simple issue of an open circuit, but... -
Hello everyone,
This is my first post after browsing this wonderful treasure trove of knowledge for many, many evenings. I've decided to learn how to fix these things, properly.
My patient is an A2338 Macbook Pro M1 (late 2020).
It had some corrosion around JT710 and JT700 caused by liquid spill, as well as against the protective barrier around the USB-C chips UF000 and UF100. So I took the main board out and cleaned it with a toothbrush and alcohol, then with alcohol in an ultrasonic cleaner. Cleaned the touchbar flex connectors as well. The board looks... -
Hi to all,
the owner of this macbook brought it to me after a fall, that hit the upper right corner of the top case.

Got this waterdamaged where oxidation happened under shield on touchbar cable. It showed image but no touch. After I cleaned and resoldered everything except ic (it is sealed anyway) i am getting touches however i find it a bit hit n miss where it works but sometimes missing dragging. Tapping seems fine. I think it might be something to do with this big cap which might be LDO or something. I placed 10v 2.2uF cap there. Anyone could measure it from good/dead touch bar lying around ?... -
I am trying to fix audio issues on a lenovo slim 7 pro im trying to repair, Has some issues with audio (sound only from bottom speakers, no sound from headphone (static) or palmrest speakers)and am looking for a schematic to troubleshoot, I suspect its something to do with the realtek ALC3306 chip, or unclean power to it.So a schematic would be useful, or any schematic utilizing the ALC3066 in a similar configuration, (2bass, 2 treble channels)
