Why my right ear not working?
I checked for the driver wires ,if it is disconnected or not .But its fine .But no sound from right *
sounds like there is a break in the cable that leads to the right ear. try narrowing down where the break is by wiggling the cable all along the length of it. once you have found the break point you will want to replace that section of wire. If that doesnt find them problem it could be that the soldering on the jack or on the driver in the right ear has come loose( happens quite often)
