X220 tablet screen cable

[86turbodsl]

My daughter's X220 tablet has a screen that is intermittently on/off. Depending on how you move the screen. I believe this to be a bad cable, and so we've been researching this problem and the HMM has 2 different cables listed, an LCD cable and an LED cable. How do i know which one is the right one?

The HMM shows them both as #4, but shows only 1 cable.

04W1775
04W1776

I want to order the correct cable and have it on hand when i disassemble so i don't have a long wait while a cable comes in.

Any wisdom out there?

Enter your Serial# (without -) here to find out what screen you have: http://pcsupport.lenovo.com/us/en/partslookup
Then look for it's datasheet to check if CCFL or LED.
