post #1 of 4
Thread Starter 
I have a U9BL-S and the backlight broke when i plugged a faulty usb device in last night. A broken staple was stuck in the usb stick's usb connector bridging the two power pins. The backlight flickered then went off and now it does not work at all. I'm at a loose end what to do as I live in UK and I bought my keyboard from USA at great expensive and import fees. Does anyone have any experience and know what the problem might be?

As far as I can tell the whole usb hub in the keyboard is totally shot too as nothing happens when i plug devices in.....

You most likely shorted the 5v pin into a data pin and fried one of the Micro controllers.

You can open the board up and look inside to see if anything is burnt.

Could be fried at the hub or even the motherboard end. Little green smt fuses. Not trivial to replace.

Be sure to try other motherboard ports.

Thanks for replies. Yes i've tried every other usb port on pc and the keyboard still wont light up nor will usb hub function. As far as I can tell there were no shorts to either data line just the two 5v- and 5v+ as the broken staple actually had a bend in it that perfectly bridged the pins inside the usb sticks connector. Also with a multi-meter I see that therew is no power whatso ever getting through the usb hub now.

I'm just waiting to hear back from ergogeek on what if anything is feasible about returns but I have a feeling il be taking it apart soon.

Does anyone have a circuit diagram perhaps?



edit:

If one of those SMD fuses is gone can i just bridge pins between them till i find the blown one?
Also are those located on the keyboard or the computer end as all my computer ports seem fine?
