I was recently given this O2 from a family member. I hooked it up and used a SNES RF adapter to get it to display on my TV. When it is powered on, I get a grey-ish screen with a few garbled letters and numbers. Any idea if this unit can be repaired? Any hints before I rip it open? https://goo.gl/photos/higwtsnwsiJeJyPW9
