I forgot, sorry.
820-01700 2019 touchbar 16 inch MacBook Pro 2019 A2141.
I’m not really able to afford an oscilloscope atm, I only have a Uni-t UT61D multimeter.
I really appreciate the help, thank you
Oh I see, thanks man. It might be possible that I haven’t soldered the gmux properly. Is there a way to check for signals with a multimeter to see if the multiplexer is doing what it’s supposed to?
I agree, I was just wondering if there’s a possibility of mux chip not working but still having image on external.
I went through the schematics but I wasn’t able to understand if the mux chip is also responsible for providing image to external.
Just trying to make sure that if I spend 600-800$...
Hello, sorry for not providing context.
It’s a liquid damaged MacBook.
backlight shorted to mux, mux was blown and was shorting one of the power lines supplying it.
Replaced it and the machine is working. It’s a laptop I bought in November, as a repair project.
There were quite a few problems...
Hello
I replaced a mux chip on a A2141,image on external but no image on the MacBook lcd
Is it possible for mux to be bad or badly soldered and have image on external?
Hey guys
Got A1534(820-00244) that is power cycling.
Takes 19-20V from the charger but cycles between 0A -> 240mA -> 415mA -> 0A
Bought it as broken, for parts. Someone took it apart before, stripped screws, stripped screw holes and metal shavings on the board.
Nosigns of any rework done on...
