Hello,

The last 4 leds of my kid's Luke Skywalker Ultimate FX Lightsaber have stopped working.

Sometimes if I bent the white strip of LED strings where it is in conect with the blue pcb they would light again so I've applied some new tin to these 5 soldering points but without any luck (and now even if I bend the white strip they wont light up):

As I want to keep the light scrolling effect when powering up and down, could anybody please tell me what should I do in order que repair my kid's lightsaber? Do you know which soldering point should I focus the get these last four leds shine again?

Thank you
