I have been to this one today, all LEDs flashing fast, I have come across this fault quite a few times and usually replacing the 10v 680uf capacitor on the PCB does the trick but not today 😥
When I refitted the board I still had the same fault, are there any other components that can cause this fault?
The capacitor that I replaced did appear to be slightly domed so I am a bit puzzled.
I am going to replace the replacement capacitor just in case it is a dud.
Thanks for any help.
