Ducky Dk9008 Dead Key
« on: Mon, 21 July 2014, 05:26:47 »
I have the Ducky DK9008 Shine 2 and has been working well for a year. So i was hoping all i need was to replace the switch or see some cold solder joint.

Recently the G key has stopped working, so I had opened it up and made contact with the two pins where the switch is soldered in and nothing appeared onscreen. The other keys work and the joint looks ok.

Should I still go ahead and replace the switch or it won’t make any difference? I haven’t done any soldering before but I don’t mind trying it.
Are there any other components I could check to see what’s causing this?



Thanks.

Welcome to Geekhack!

If you've already tried shorting the pins (the ones a bit diagonally either side of the "G", right?) and still didn't get anything, that would tend to suggest another component.

If it was a broken switch, that should have caused the keypress to register.

If in doubt, really press down to cut through any flux that is covering the solder joints - I would tend to use two pointed probes and poke them at the solder blobs for the G switch.

If it was a broken trace, it would probably affect other keys in that area, which you said it doesn't.

Perhaps one of the other components around the G?

Thanks for the welcome and reply.

That is correct, the two pins diagonally were the ones i tried shorting with some probes with no success.
Could it be the diode? and how about would i go testing that?

It could be the diode. You should be able to test diodes with a multimeter.

I tested it with a multimeter and its showing the same as other diodes, so i believe its working.

Anything else to try or look at a new keyboard?

Edit: So i tried shorting the pins a bit harder this time and manage to got it to work but couldn't repeat it. So maybe i should remove the switch and see.

Yeah just resolder it or if that doesn't work replace it.

I just tried resoldering the part and now it works great. Thanks for your replies.  :)
Wish i tried this before waiting 2 weeks for the replacement key lol

A happy ending :)

You know now, in case it happens again.

Repair of mechanical keyboards is possible, and often is not as difficult as people imagine.
