Burnt pin

[ccgllc]

Hi all -

One of my S9s keeps dropping one card.  When I examine it, I see that one pin on the power connector is off-colored compared to everything else.  Often just resetting that connector will get the card up and running... for awhile.

Is there any way to clean that pin?  What would I use?

Most electronic stores (or Amazon) carries electrical contact cleaner - use that on both connectors. Make sure it is clean and dry before re-applying power. Also, try to adjust the pins to make the best contact possible - i.e. carefully use a pair of needle nose pliers or whatever you have handy to compress the female connector and expand the male end for a good tight fit. If the connector is too burned up, you need to replace it.

I like using a touch of conductive grease on my power connectors.  Make sure to buy conductive, NOT dielectric.  They are opposites.
