Last night I assembled a Midiboy which booted correctly to the Blokas logo screen on power-on.
However, this morning, when I tried to boot it up, the screen would not power on. Midiboy doesn’t show up on computer either.
My question is: Which solder points would be suitable for diagnostic purposes with a multimeter (and which voltages should be visible across them)? Although my soldering is far from perfect I can’t see any obvious mistakes in the assembly.
I have already tried a fresh battery so the obvious reason has been ruled out.
