still a short between pin 7+8, and another crossing 10-13 remain.
Daniel, that's fine. Please check the schematics for IC407. Pin numbers 1 to 14 are going at the left side top down und 15 to 28 at the right side bottom-up. Pins 7, 8 and 10 to 13 are all connected to GND.
You should find also a GND at pin 23 and 27 and a connection between pin 6, 9 and 22 all connected to VCC via L402.
