I have built the K8055 and when I plug it in LD11 (Power) turns on and LD4 flashes once, and LD8 flashes once very weakly. Help me please!
Please check all the soldering.
Check also the IC3 is properly in the socket.
The I3 is fine, can see no visible problems with the solder but I will check again.
Edit: I fixed it now, thanks
