Rainbow 4x4x4 LED Cube troubles shooting

Received and completed led cube kit. Once powered on only layer one of LEDs will light. The remaining 3 levels are dark. I am looking for troubleshooting guide for fix.

Any ideas?

Thank you,

Dustin

Please check the bridges on the side PCB soldered well.

Thanks will try. Strange setup with respect to the SMD/SMT configuration of the jumpers they should have just included some jumper wire and made it TH design. :bulb:
