Isn't that enough to consider it burnt???

You're absolutely right, it’s burnt. In the meantime, I soldered another 4.7-ohm resistor. After powering it up, the USB tester showed different values. Then I measured the resistor again, and the new one was also burnt, reading 4.7 kOhms. Something is burning this resistor. Can you confirm that R7075 should indeed be 4.7 ohms? If so, what could be causing this resistor to burn?

Change both C7075/77...

Thank you for your support. I replaced the two capacitors, but it doesn't seem to have had any effect. However, the customer called me and said they bought a new computer and no longer want to repair this one. Thank you, you are amazing!

Did you also replace R7075 again?

Make him an offer and get the Mac; not too much money.
It can be repaired probably; or you keep it for spare parts.

I didn’t change r7075. I have hasked to my customer 80€ for reapair. However, I also offered the client to purchase their broken computer, but they said they would think about it and had it returned to them.
Then if you want you can close this post
See you to the next repair
