Hello everyone. I have a problem with audio on my A1297 (820-2849-A) The built-in speakers on a laptop stopped working. When I move the audio jack (port) the sound comes and goes. According to the most popular solution I have tried to short the contact with the help of toothpick. After that the sound has gone completely though In the OS the sound card is enabled and active. Unfortunately Im unable to take my laptop to Apple Service Center since I bought it in the US but Im a resident of Russia. Repair in Russia is possible but its very expensive and time consuming. So I disassembled the laptop myself and realized that the audio port is to be replaced. I failed to disassemble the entire logic board therefore I cant understand which spare part I need to buy to fix it. If you could offer me your right solution or give me the part number the of audio input from the logic board #820-2849-A or schematic I would highly appreciate that.
