    Had my 3TB HD crash and did the repair myself. Surprisingly not that bad cutting the tape and opening it up. Watched enough video's for gotcha's and have a replacement tape kit ready to go. BUT, system is restored and working perfectly except for 2 big bars on the screen. One is right center about an 1.5" wide with left of that 2 1/16 or 1/32 bars. Second major bar is about 2"inches wide and about 1.5" off the right side. Tried reseating cables a couple times. Any opinions out there on if I have a bad Video card, bad cable, or I really did "break" the LCD display?

    Bars appear to be dead lines not video black imposed. I have a second monitor off the lighting port and it is working fine.:confused:

    You narrowed it to either the display or the cable. My guess would be the cable or its connection. Start with the cheaper of the options.
