I have one, just like this.
Did you, or anyone figure out how to fix this?
Dash still works, just very dimmed.
Changing lcd, does not help.
Plug in other cluster, that is fine.

For now, we will exchange cluster.

I also found this on dk.

did not find a solution yet

has nothing to do with filter or similar can-bus elements.

the problem is on the main board, thats for sure, but where......

Thank you!

Is this a Johnson control flaw.
Are the vdo cluster better?

I have the same problem on W447 instrument cluster, display work but no backlight. I am contact minitools.com and they told me that problem is on main board. Anyone know where is problem ? I need to repair myself. I can not send it to outside country.
Thank you

Both of transistors are okay, tested with component tester and also replaced. All resistors around them are also ok.

I had a similar error, I had ripped a small capacitor and its trace in top right corner of cluster (from back), repaired trace and checked continuity, all worked fine afterwards.

I have the same problem. Anyone know the solution?

Hello ! I have same dash with same problem, bought new LCD but still no back light, but graphic and all working OK. Mine cluster dont have CAN filters or any of that. I've also heard about BCP53 replacement and component in surrounding , but nothing. Now Im re soldering all bigger resistors. Does anyone have solution, I have dash on my bench for testing.

Best regards
