They brought in a MacBook for work that had problems with the display backlight, but when they tried to repair it, it stopped turning on. What could have gone wrong? 😂

Hello there
I have problem with Macbook Pro 15" 2017, model 2017, MB code 820-00928.
I bought it as broken with some artefacts on the screen, first I thought that this is problem with ribbon cable but after inspectiing ribbon cable I know it is fine. I tried to reinstall macOs and then I figured out that this must be something with GPU as installation freezes at the end (when drivers are loaded). I installed Windows and was able to install every each of drivers except GPU driver, as soon as I tried to install GPU driver - black screen and restart.

Hi,
I'm having an issue with an A1707 MacBook Pro—there's no audio output. Initially, the MacBook came in with a no-power problem, and I found a faulty U6400, which I've now replaced. The laptop now powers on, but there's still no sound.
I've also replaced U6300, but the problem persists.
Here are the current voltage readings:- PPV18_S0: 1.8V
- R6402: 1V
- R6405: 1V
- R6403: 1V
- AUD_SPKRAMP_RESET_L: 1.3V
- PPBUS: 12.6V
