Hinges broke, first one then the other. PB continued to work no problem for another month. Then on startup. POST as normal followed by grey logo screen then blackout. After approx 10 attempts, grey logo screen no longer appears after POST, but black screen with variable 2-5 pixel-wide horizontal band across full width of display. No external monitor at moment to test hardware output so any symptom recognition and thoughts appreciated. ---------- Just to add, PB works fine, boots into TDM, so I'm thinking either cable or LCD. Any usual suspects?
