Actually, I did read what you wrote. You stated that this has been going on since shortly after you got the device.
There is no date info no when purchased, and no mention of if you have contacted the manufacturer on this at all.
Since you did not mention when that was, although it would seem odd to have this kind of problem for a long period without seeking to have the seller or manufacturer resolve it, it seemed to be something you recently got. If it is less than a year old, then it should still fall under warranty. Unless of course it has been damaged in some way.
If under a year since purchased, then any issue with it should still be covered under warranty. Also, if under warranty you would not want to open it up yourself as that can void said warranty.
