everything went well but the initial diagnostic

내 문제

No sound was coming out of my iPod 5th Gen 80G, and I Didn't want to buy a new product

나의 수리

went well, but the product (Ipod 5th gen 80Gb) didn't work after the replacement, as the issue came from the logic board, and not the headphone jack that I just bought

내 조언

would be nice to know how to repair the "sound related" defects on the logic board of the iPod 5th gen 80G.
