Kylo ren wiring help

Im converting another kylo ren fx lightsaber but I'm in the wiring test part but it only turns on for a second with lights and sound and then turns off.

I'm using the stock leds for the side blades and a rebel star deep red for the main blade. Attachment 14334Attachment 14335Attachment 14336Attachment 14337

those joints look pretty cold I would recommend resoldering those or the joints will break off. Also you need to solder wires to the actual board itself. take a look at shameems post again. I havent done the conversion yet and I plan on it after christmas so I will let you know.
