tips for fixing the c-shaped grip inside the jack
there are tons of ipod disassembly guides around, i suspect its one of 2 things, the jack usualy is C shaped on the inside, the main problem is that when a cheap jack is used or too much stress is applied to to the jack, that C expends and dosnt manage to get a decent grip on the headphone jack, solution : press on the C shaped grip to compress it a bit, should solve the issue,
or bad soldering/constant stress have damaged the solder points of the part, so you will need to repass the solder points and make sure theres no cracks in the pcb,
I'm not sure if you're still active on this thread. but i'm one of the many with the headphone jack issue. i opened it up. and one of the screws was out, so i screwed it back in and closed it up. the problem wasn't fixed. so my next step is to check that c-shaped grip and try and make it tighter. before i do it, i was wondering if you, or anyone else who reading this who knows, can give me any tips on not messing the jack up more. i didn't remove or look at the inside of the jack when i took it apart previously. any advice is greatly appreciated. thanks in advance!
