Hi OsKArg,

I assume the AC was power up, I also noticed the switch was on Sports, did you try the other way?

Hi OsKArg, for your issue, I'm afraid that it cannot be solved by refreshing firmware. Sorry about this. Therefore, I sincerely suggest you refer to the above and send the unit in for diagnosis.

We do not have an official service center in Argentina for now. Sorry about this. If you have friends in the United States, you may check whether they can help you send the unit in for service.
If not, please kindly ask the seller or local dealers help to send the unit in, thanks!
