Question is there a difference between screen cables?

[EigerTroll]

I have a Satellite P50T-B
The screen cables is 1422-01QK000. The connector at the motherboard end had disintegrated!! There was no backlight to the screen but I could read it with the aid of a bright torch.
I ordered a replacement but it is a 1422-01PY000. The website said it was for P50T-B
I installed the cable but the screen shows nothing at all.
Is there a difference between the cables?
Do I need the correct cable?

Make sure you have connected the cable properly including the ground connection.
The cables might be different if the have different part number....but sometimes it might be just the same cable.
They might look the same and they could fit but the wires could carry different signals.

I unplugged the cable to reseat it to be sure and the ground wire came adrift. It looks like it was not attached properly. I will have to try and reconnect it somehow. I am hoping that I can just resolder it.
