did you replace those parts you removed with brand new ones or did you just clean them up and put them back? also what was the tool you used to heat up the components and remove them? also how can you tell with the multi meter which components on the chip are working properly?
I replaced the parts with components salvaged from an old scrap board. To heat up and remove the components, I used a soldering iron and a heat gun. As for checking the components, I used a multimeter to test continuity, resistance, and voltage. For example, diodes and capacitors can be checked in circuit using the diode or capacitance settings, while resistors and connections can be verified with the resistance mode. If a component shows unusual readings, it’s usually a sign that it’s faulty.
Test with a different AUX cable; a damaged or low-quality cable can cause buzzing,,, may be Ground Loop Issue,,, or Dust or debris in the AUX port can cause poor connections. Gently clean it using a toothpick or a small amount of isopropy l alcohol or WD-40 on a cotton swab

Is the 4 big blck in amplifier boatd is capasitor or not?
No those are coils
how to fix buzzing sound when connected to aux? bluetooth no problem.. only when aux it keeps buzzing..
