I just noticed you didn't install last bootloader and firmware.

You should install them.
Specially the bootloader 1.10, that makes firmware from USB Stick possible without opening the PreenFM2.

Also, did you remove JMP3?

Once flashed you remove that jumper so it boots as normal.

Does your USB stick flash as if it is being accessed? if you are in DFU mode the light tends to flash once and then go out. Mine flashes a few times upon normal bootup before going to an idle state.

Mine's a Sandisk like this one, it glows when idle. (I put some tape on the back as a safety precaution ;))

Yes, he did that right, he has the midi and audio working.
That really is a LCD problem only now.

Hi Tenchi,

Here are all the LCD connections.
Please check them all.

(Sorry i changed the color signification since last picture).
Check green point are linked together and to the ground.
Check red ones are 5V.
And that the grey/blue one (LCD pin 3) change when you turn the variable contrast resistor.

Then your multimeter into shortcut detector.
Check every orange connection from the CERB40 pins to the LCD pins on the other side.

And let me know the result,

Xavier
