Greetings all,
I've recently received this S423 board and was testing it. It works just fine but the PS/2 connector doesn't work. The three keyboard LEDs light up for a split second but then the keyboard is unresponsive afterwards. I tried doing some troubleshooting and so far the only thing I can see wrong is this SMD Resistor Network (labeled "RN1"), it shows no resistance and no continuity. Also there is no marking on top of it. From the best photos I can find on the internet I see there is something written, but can't make out the number from the low resolution. This makes me suspect that the component is burned or bad from factory. So I kindly ask if anyone has this board at hand, please let me know the value (3 digit nr) or even better take a photo if possible. Thanks in advance!!
