Question Logitech G810 rgb lights not working

[Andrew_Liew]

Some time back my g810 stopped showing the lights. I think a fuse burnt out or something from too much voltage, there was a burning smell. None of the lights are working, not a single one, which makes me think something is wrong with the power supply. I opened up the keyboard but don't know how to proceed. I've looked for damage but can't find any. I've got a multimeter and soldering iron handy. although I'm a beginner at electronics. Could anyone give me advice on how to proceed? I can provide pictures if needed.
Thanks
Edit: It's hard to see, but I think I see a faulty component. It's loose and smells burnt, also has white powder next to it. Next to Q6, under r216. I think thats a transistor?

the resistors also look a bit brown...

That does not look like it's fixable without replacing the board.

Could you explain more? I was thinking of just replacing the damaged components?

You can try but the damage looks to have burned through the PCB layers which you can't fix
