PokerX pcb issue?
« on: Thu, 08 May 2014, 08:24:45 »
Hi, I just got a pokerX pcb in the mail, and I can't get the - [ ' keys to work.

At first I thought it was just a bad switch or solder joint, but I can't even get the key to activate by tripping it with a wire to complete the circuit. The pcb pad joints are not lifted or damaged it seems.

I don't know too much about PCB's and circuitry, but it seems like the affected keys are all connected via the pcb in a string like fashion.

I was wondering if anyone would have any ideas why the affected keys are not working?

Could be a bad SMD diode (or a bad solder joint on that diode). It would require reflowing the solder or replacing the diode.

this is the SMD diode correct?



Do you think I could find a replacement at a radioshack or frys or other local electronics store?

I also I have a quickfire rapid that I could potentionally steal one from.


Do you think that one bad diode could affect multiple keys?

1) Yes that's the SMD diode.

2) I'm not sure about Fry's but maybe at Radioshack? I usually see people ordering those from Mouser or Onlinecomponents. And harvesting them is obviously a possibility.

Is there any way to determine which one may be bad or how to test them?


from what I understand, a diode directs the flow of power, and if they are wired in a chain, if one switch isn't getting power ( which its not ) then i would kill the switches behind it?


I bought the PCB off a memeber on here, and I would like to get it working as I was told it was when I bought it.

well i took off one diode on a switch i know to be good, and I could just hard wire the diode and the key would trip, tried that on the bad ones and still no dice.

I guess its just dead.
