Chosen Solution

I have taken apart my MBpro TB and found that 2 or 3 gold connectors have corroded on the flex cable connecting the display to the motherboard. Not the separate display mobo but the cable coming from the motherboard. That is connected to underside and display assembly. After cleaning MacBook out i tried reversing the connection to rule out screen being faulty. Nothing. Anyone have a spare flex cable? Willing to pay all shipping for it. Or anyone know a trustworthy medium that would sell just the cable? update: added pictures Where

Sounds like you need to replace the flex cable, no? https://www.ebay.com/i/132408057873?chn=

Nice, i washed this little flex cable and the connector on the mobo, and everything just worked. did not expect that

Could anyone say to me, if this could be my issue ( I do not habe Idea what it is) and cannot clean?
