I changed the left speaker with another one got on ebay. but still it has refused to work. what other methods can i try?
Stellar guide, easier than it looks at first, new left speaker from China, perfect sound once again in this 11-year old MBP.
I did this disassembly and reassembly in 2018 when I thought my GPU had another breakdown. Should have replaced the left speaker back then. In the end it was the RAM and replacing 4GB with 8GB did the job. Still have to do this again to replace the speaker, if I can get one on ebay. I brought it to a repair shop to fix the capacitor of the GPU board in 2019. Hopefully I will never again have to pay Apple 350€ again, to fix a problem they caused with areplacment of a faulty part with a NEW faulty part! Real Geniuses those people .. when it comes to making money. The company was better when Steve Jobs was still alive and shareholders got nothing for their shares!
Todays Macs are a nightmare to repair. What a difference my old Quicksilver PowerMac G4 is! You press one button and the whole chassis opens up for repair, maintenance or upgrades without removing one screw!
