I called JVC support. After 24 minutes, I was helped.
I told the guy I had the cover off but did not see anything to activate the drive.
They told me to take the remote & hit the power off button & hold it for at least 10 seconds. AUTO came on. I hit the tray open button, & nothing happened. Tried again, no go.
He said it had to be serviced & offered to give me a service center name in Hawaii.
I said no thanks, & took another closer look where u said to look. Found the white button & voila....
Thanks, & Aloha.
