Hi my name is ***** ***** I will be the expert working with you today to help and resolve the problem you have posted.
I am sorry to hear that you are having such trouble. I will try my best to help you out and resolve the problem as quick as possible.
If the unit is 3 months old it must be covered under manufacturer warranty. You can get the LX830 repaired or the faulty parts can be replaced for free.
Let me know the make of the manufacturer i can give you a warranty support number to call up and fix a schedule for the repair.
