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,


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:
