Note to mods: I couldn't figure out why you needed my actual birthdate for me to sign up for an account, so I made one up. If this is a violation of the rules, please let me know. I have an old STL-11000 that powered up last month, but will not power up now. I know I probably need to send it in, but what I'd like to know is if it should power up immediately when the power cord is connected or whether it needs to see a connection attempt via USB before powering up. Thanks.
