      So, I’ve been using my 1.5 DIY kit for quite a long time, but it recently stopped working suddenly.
      First display wouldn’t turn on but it was due to a loose weld in display (near Q2) probably moved during a trip. Fixed it, it worked for a few days, then something happened and ossc won’t turn on at all.
      Now when I turn it on, there’s like a real small flickering in the display, but nothing else happens.
      Any idea on what to check?
      Thanks!

        You should measure all regulator voltages and ensure they’re within spec. One possible cause is a cold joint on FPGA bottom ground pad. If you see VCCINT voltage deviating from 1.2V, try reflowing the bottom pad.
