hello, I have a thinkpad t61p that I cracked the screen on, so i bought a cheap repacement off of ebay (stop s******ing). I swapped it out (I'm a computer engineer - I was comfortable doing this) and due to it being a cheap replacement (...I told you to stop s******ing) it wasn't a great fit. I guess due to the jiggling to get the blooming thing to fit, the ribbon connector on the back became detached and all i was getting on boot was a white screen. I connected the ribbon and now I get no display - I get a very VERY faint 'thinkpad' splashscreen on boot and a decernable change on the display but thats it. I connected the original cracked screen and got the same whereas before, the broken screen was still displaying on half the screen. I connected to a vga external monitor and the display was fine. Any ideas? Have I blown/shorted something else when the ribbon detached? Cheers - Didnap
