I am trying to replace a motherboard ribbon connector as circled in the image on a amazon fire 10 where the flex ribbon cable slides into that the previous owner messed up. Is there a way to determine the number of contacts and pitch of the plastic connector or an easy way to determine the exact replacement connector I need to buy? Don’t know if it helps at all but on the flex cable itself there is a number 1 written on one corner and number 51 written on the other corner which is also written beside the connector as you can see.
@ntec those numbers are the position of the pins. Number 1 on the connector has to correspond with number 1 on the cable. It is not useful to find a replacement. Since there are no schematics available you would really have to do some tough searches at places like mouser.com digikey.com for something like this to see if you can find a match.
