PCB problem

[sitch]

Hi guys, I have recently assembled a pcb but all the LED doesn't light up ( correct polarity ) but the key input is all working as normal. May I know what probably caused the problem?

What PCB are you using, can you upload pictures, are you sure the polarity is correct, are they just maybe turned off in the firmware?

I'm not sure I can help, but if anyone can you'll need to give us more information

Hi Im using china GH60 pcb replica, I think it's running on GH60 firmware too, yes Im sure of the polarity.

Is it possible to turn off in firmware? How do I check?

I don't have a GH60 (China or not), but I'm sure there are people here that do and help you more than I can. But I know on a lot of boards you can turn LEDs on and off and set it to a key combo to do so.
Do you have a tool to configure the board?

Even if you are sure, it's always better to show some close up pictures and screenshots of firmware settings. We all make mistakes.

There are many dodgy unofficial Chinese "GH60"s out there, if you have a spare LED touch it to one of the soldered ones with the polarity reversed - it will either light up dimly and confirm the markings on the PCB are wrong or it won't which will prove nothing, but it's a quick check so worth doing.
