Well as the title states, it wont power up. It has a 4 point connector at the back of the unit: illumination, GND, an empty one and B+. When B+ and GND are connected and I press the pwr button or hold it, nothing happens. I took it apart, and there are no burn marks on anything inside of it, also I checked that the connector pins and the PCB rails are all good and that the voltage applied reaches the pins and PCB. Didnt see any fuses tho. If someone has a schematic or has done something like this, maybe some advice and help.
Thanks! Last edited by mekaiver; 27th August 2011 at 07:20 PM. |

I don't think it will function like that. Hopefully someone will correct me if I'm wrong.
