SMD rework
After assembly the yellow LED blinked as expected, but the LED matrix stayed dark. I checked the SPI lines (clock, data, latch) and the clock line was pulled to GND for some reason. Luckily I could remove 90% of the circuit from my search due to an intelligently placed jumper. Nevertheless I removed one SO16 shift register after enother and the short still was there :-(
