First of all, my english is not very good, i'll try to make myself clear. A couple of weeks ago, I cracked the LCD display of my MBP 2.2 ghz A1226 (Santa Rosa). I found a really good deal on eBay for a complete screen assembly (lcd, front and back bezel, iSight, etc), it was really cheap and supposed to be tested and working so I bought it. I received and installed it today, everything went good but when I turned on my MBP, the image on the lcd had horizontal lines moving in it. The screen is glitching and all fuzzy. When I plug the MBP on an external display, everything works perfectly so it's not the graphic card. What could cause that problem ? Bad cables, bad lcd ? I made a video with my iPhone , the quality is not perfect but you can clearly see the problem. http://youtu.be/lp7EXeXVx14 Thanks alot !
