Hello phil. We wouldn't recommend attempting to repair the phone on your own, as it will void the warranty. We'd like to review our options to help you. How long have you had that phone for?
In that case it is no longer covered by the warranty. In any case, you could still call LG to inquire about the repair. They might be able to repair the phone at a cost. You can call them at 1-800-793-8896.
