Hi Latigid, It was the "J15_S not jumpered to 3.3V". Sometimes things that seem so complicated are so simple. I'll buy you a beer Thanks very much! Pieter

Hi guys, I have been (silently) following Midibox for years and some time ago I made the decision to build the Midiphy SEQv4 myself. Everything went pretty well (great video instructions!) until the very end where I put it together into the box and the left display would not show anything during and after booting. When I press some keys random characters will show up on the display. I have now stripped down everything to a bare minimum (Core, usb/sd, 2 x display) and the problem still exists. I have tried swapping the display cables on the Core, if I do this the problem moves to the other display, this should rule out a problem with the display or the flatcable. I have attached a picture of what I see after booting. I hope there is someone here who could give me a hint on where I should start looking to solve the problem. Thanks, Pieter
