deskthority

So got this with another pickup and am rather bewildered by it. Absolutely nothing, no life at all. I've tried straight PS/2 on multiple computers and with an active USB converter...

From what I can see its not getting any voltage, checked with my multimeter.

Pin out is:

Yellow = VCC
Black = Clock
Blue = Data
Red = Reset (not used)
Green = GND

PCB looks fine with no corrosion, nothing is obviously wrong so I'm rather stuck with this one It has a power light too which is actually really helpful in this case. Also checked the continuity of the cable and it's all good.

Heres some pics:





Any help is greatly appreciated Really want to use this thing

try and replace the electrolytic caps like the one just left of the power input if the power is working it means there is probably a bad cap or broken solder joint somewhere that will be causing it not to work.

I had one of these in a similar situation... the power LED would turn on but no input at all was going through. The caps were still measuring alright, so I did some poking around elsewhere and determined that the controller likely failed. I cut my losses, took off all the switches and bought one of these instead~
