I purchased a TS 501 less than 1 year ago and it would no longer power on. Sent it in to Autel for repair and they could not get it to power on. So the 501 is no longer available and Autel would not honor the 1 year warranty because it was purchased from The Autel_shop online, and they say they are not an authorized dealer. So why is the tool warranty not in effect? I had to pay $100.00 to get the ts801 to replace my 501.
