LCD Display not working, always white and random bars
I have a MacBook Pro 13-inch, late 2011 which some time ago started suffering this  issue and I was wondering if do someone know how to ensure if the fault comes from the LCD cable or the LCD display?
I've tried disassembling the MacBook to check for cable connections, I even tried removing the LCD display and attaching an external one via thunderbolt to HDMI connector and it worked fine on the external display. In fact attaching an external display i'ts the way I've worked around the problem.
Also I've tried resetting SMC, NRAM and PRAM without luck.
In case i would need to replace the LCD display, I also would like to know which ones would fit better on the MacBook. I mean, over the years Apple improved LCD display by providing better image resolution and lowering power consumption so i would like to know which technical data should i look for in order to know if the new LCD Display would work on my MacBook while checking for those improvements
