The right earphone do not play sound but left is OK
What can I do?
Gonzalo, take a can of keyboard air cleaner, you can buy those at any dept store. the ones you get to clean your keyboard etc. Hold your ipod upside down and blow a few puffs of compressed air into it. Take your headphones and plug it in and out a few times in succession, since this may free the stuck contact. If that should not work for you, you will have to replace the headphone jack. Good Luck
Before taking the device apart, you should try it with another set of earphones, just to make sure that the problem is actually with the device as opposed to the earphones.
i have this problem on my gen 1 nano, try and get a replacement jack, i did read that the part is mechanical so you could try cleaning it with a cotton wool bud and see if that helps, hope this works
I have tried with another earphones and I have the same problem.
