Probably only a 90 day warranty but you should have 1 year on parts. Check to see if it will void the part warranty if you open the unit. Or just take to authorized dealer. Sounds like the control board is out. This is part of the keyboard where you enter commands and also contains the clock. There are components on that board which can be replaced, but if it’s still got the warranty on that board you are entitled to a new one. Labor cost is not covered. Also, if you don’t currently use a spike protector on the power cord, please use one ongoing. This greatly reduces the chance of a repeat of the same problem even with another unit. Hope this helps you.
