Hey Guys,

I have 1 Blue Powercell light (D7) not coming on with allthe others. Otherwise it works perfectly.

It does light up when I apply a battery to the individual light. So the LED is still functional.

Any ideas how to trouble shoot this? Is it the cord from the amp Sound board to the [Cyclotron](https://www.gbfans.com/wiki/equipment/proton-pack/cyclotron) lights?

Its the GBFans kit.

Please help!

Now I don’t think the led is functional. If it wasn’t would the rest of the blue ones still work?

Can I take it off and re-solder on another blue led?

It sucks having only 1 not working.

Any ideas?

It sounds like a bad LED. I would PM Spongeface or AJ for more information. Both would be more than willing to help

Also make sure the [ribbon cable](https://www.gbfans.com/wiki/equipment/proton-pack/ribbon-cable) is seated correctly. Had a similar situation with the thrower [bar graph](https://www.gbfans.com/wiki/equipment/proton-pack/bar-graph) and that was the problem.

Hopefully you didn’t apply direct and full battery power to the LED itself. You may have damaged more than the LED doing that.

Otherwise, I sent you details to have it sent back for an LED replacement.
