Ok, most uninformative subject tag aside.
My Ducky DK9087 Shine II TKL has an intermittent ESC key.
How to repair?
resolder joints on the switch prongs
or if it's a cracked trace some where on the PCB.. you have to bridge the connection
No other way to fix..
It might sound intimidating, but GH has amble members who knows PRECISELY how to fix it.
And we can guide you through it on Skype if necessary.
