Separate lighting system. 12 volt LED strip. If you have 12 volts DC at the connector, you need a new one of these :

Welcome to the WOZ light board issue club!

Bad connection somewhere.

LTG : )

Classic led lack of voltage issues. White requires The most voltage. The more it drops The mord towards red color then flicker and nothing. If you have flicker but decent voltage, it's probebly The data line..

I asked in Another thread whats on thoose boards, if it aint to much other stuff you can probebly wire it and skip The board.

Are Therese two on the same board?

Maybe follow The wiring with the voltmeter and see if you can locate The drop.
Is this a singel led?
If it is and it produces more then one color, there should be three or four wires connected to it, which is important. If there is three, you should be able to lend twelve volts somewhere. If there are four, you pretty much need to find why and where it is dropping.

My lights have been out for months. I’m going to take all the cables off and reseed them all to see if any are loose. The cables are a very poor design.

I had the same issue with my Throne room. I disassembled it so the strip was free. Pressing firm on the strip showed me varying levels which told me it was a bad connection inside the strip. You can buy a replacement from JJp. That’s what I did and it’s working as it should now. Disassemble it and fiddle with it to see if you can manipulate the connection.

Good luck

I had to troubleshoot some lighting issues myself. Had an issue with one of the small GI boards that ended up needing to be replaced. Mine doesn’t have 2.0 boards. If you have the original style and your issue is GI board based, you can get spares of that too. Or swap around to a different similar board and see if the issue moves with the swap to help identify your problem better.
