Its almost 2 years since some inexperienced ass hole in the school tech crew sent 25v down my l70's headphone jack. There is crackling and poping from the right channel and they just laughed at me and said claim on warranty, obviously i cant and its immoral. Didnt even offer to fix it just became a running joke in the tech crew. This happened only a month or two after i got the phone when it came out. So almost 2 years on and not being able to listen to music on it is driving me up the wall enough to eradicate every member of that crew so any ideas on if the audio jack is replaceable and what other fixes i should try. Rude f**ks ruined my amazing phone months after i got it.
