Acer lcd cable


May 21, 2016
I have Acer Aspire 6930 laptop.
the lcd cable is going bad because it comes on and goes off when movi g the lid..
the big problem is:

I bought this cable off ebay

it is rev3

when i put it in all i got was a really messed up lines and white screen.
thinking that i got a bad cable, i got another, same deal...the original cable which i have to use works fine except when moving the lid..
the cable has mecdd0zk2l, there is no revision...could it be they changed something on the cable with the revision...I am going to buy a used one that has the same exact numbers except the last 3 digits on the second set which i figure is just the number that came out
