"[V]ertical black lines on the left..."
I hate to say this, but it sounds like a broken substrate. I hope I'm wrong.
HOWEVER, I have vertical black lines in different places on my cosmetically spotless Oasis 1. I suspect a cable may be at fault. It now sits in a drawer. I would love to use it, but don't know exactly how to test it. (Keep in mind where I live.)
ADDED: There's nothing else wrong with mine, except for some black lines.
