Help! Speedo cluster not lighting up after installing PCB's......

I'm having trouble guys......I recently installed a set of Hecklers PCB's into my gauge cluster. Since installing none of them light up, I've tried soldering the connections the opposite way around to make sure i had them the right way. And also tried clamping the wires to the pcb's on the circuit board under screws labeled '+' and 'g' and still get no light.

 

Now i just went to the car and tried giving the pcb's there own independent power source and each time when i power one of them all 3 light up so the circuit is complete it just seems it's not getting power! I checked the fuses in the engine fuse box and they are all fine. What could this be!?!?! :(

 

Are there any interior fuses that could have gone? For what it's worth the indicators still work just not the PCB's......

Did you take all the dash panels off to get the cluster out?

 

If so did you disconnect the dash light potentiometer on the right hand ignition panel. If you have disconnected it and forget to reconnect it then this could your issue

So this is turning into a pretty strange problem now guys.......the pcbs are getting power i checked by using an led attached to 2 pieces or wire. I plugged the dials in then touched the wire on the positive and negative terminals of the pcb and it lit up. I checked the connector to the dials the same way, lit up. Ive had the dimmer switch out and its fine and the heater controls are working fine so it cant be that, i checked all the fuses by the drivers foot, all fine. Ive also tried the pcbs soldered both ways round so its not polarity.

 

Please help........
