No midi IN (SOLVED: SOLDERING ISSUE ON PIN5 OF 6N137)

Hello,

I need a little expertise on that one. It is my first shruthi build with a kit provided by Olivier. LCD works and displays all required information. Buttons, potentiometers and leds work as expected.

I don’t have the MIDI IN symbol. I checked the wiki.
The orientation seems good, with the dot pointing towards the MIDI switches.

When I remove the 6N137, PIN 8 is at 5V and PIN 5 at 0V. As expected.

When I put the 6N137, PIN8 is at 5V, but PIN 5 is at 4.64V.

Does it mean I have a faulty chip?

Best and thanks for your time,

It might be that you have a bad solder joint on pin 5 so that it is not connected to ground.

Remember people… If it reads 0V it does not mean that it is connected to ground!

That was it. Thanks.
