Title: PCB problem
Post by: sitch on Sat, 12 December 2015, 05:23:57: 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?

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?

Do you have a tool to configure the board?

Post by: suicidal_orange on Sat, 12 December 2015, 08:12:29: 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.
