After making a blob on the legs for the resistor, as if the space under the resistor had burned, I scratched a piece of the PCB to get to the tracks. Is it still salvageable?...

Help in recognizing the components on the BOSE amplifier board
Hello, I have a problem recognizing the elements marked with blue dots, unfortunately BOSE does not provide any boardview. What could it be? Foil capacitors?
BOSE board number: 283394-001
Thank you... -
I bridged the resistor, cleaned the flux residues and soldered the BIOS chip to test, now I get a constant voltage of 1.45V instead of 3.3V on pin 1....Leave a comment:

Thank you for the correction, I am sending a photo and ordering the missing resistor. Unfortunately, someone was there before me and I have to clean up the flux remnants...

Macbook pro 13 A1708 Low voltage on bios chip
Hi, While trying to unsolder the BIOS chip, I accidentally blew out the R6130 capacitor and now I'm wondering what kind of capacitor it is because I don't know which one to buy. Getting to the point. The Mac draws 20v and 0.330A and does not turn on, it is dead. On pin 8 of the BIOS chip (U6100), the meter shows only 1v and then drops to 0v. After connecting the USB tester to the board itself (with all ribbons disconnected), the board consumes 5V and 0.024A
Where could the problem be?
