thanks for that clear drawing !
The connection between the pin (7) of IC3 is connected to LED's, so that seems to be OK.
So it should be a short?
What I noticed is that there is no resistance between pin 7, 9 and 14.
Between 9 and 14 seems normal, but not sure why it is also interconnected with pin 7, I can not see any short and they are quite far away from each other...
thanks !
