Hi HerbPean,
We're very sorry to hear you are unhappy with the service you are getting.
The unit at hand has experienced massive corrosion as can be seen in the images below:


These are just a few examples, there's extensive rust and corrosion damage across the boards. This damage can only be caused by exposure to either extreme low temperatures, very high humidity, or both.
The unit has been damaged so badly it can only be fixed by replacing the boards.
We take pride of the quality of our units and service yet even our units have their limit, just like any other electronic device.
Our customer service has RMA several units as I'm sure the forum members can verify, however we cannot cover damages that are caused by improper maintenance.
Our team will continue to work with you as best they can to help you out and will be happy to continue doing so in the future.
Regards,
Gadi
I've fixed hundred of the new LG electronics that were damaged in sea water. Usually only needed replacing electrolytic capacitors.
That was five years ago, and many of them are working today.
