Pin2DMD color Issue: Black screen and LD4 blinking

[Fabio_Spartacus]

Hi everyone, I received a first version Pin2dmd color display, I connected it to 5v, but when I turn on the pinball machine the screen remains black.
On the back, the power LED is on, while the LD4 LED flashes red (see attached video). the DMD was on a medieval madness and now I'm putting it on a Creature. I also tried deleting the psd and pal files but nothing changes. what can I do?
Thank you

Are you sure there is a firmware installed ?

Hi lucky1 , thanks for your answer.
After your message I tried to install the fw, but I received the error "ST Link device not found"; then I read another topic where you indicated to power the DMD because the USB connection is not enough to power it. I didn't turn it on, i'll try again tonight and update you.
In the micro SD there was already the activation file and a .PAL and a .DAT file, should I leave them in?

hi Lucky1, i tried to redo the whole procedure but I still get the same error:

 

 

I connected the DMD both to the USB socket in front of the micro SD and to the one next to it. Then I turned on the pinball machine but it doesn't detect the DMD... what can I do?
Is there a way to reset it to factory settings?

This is the ST-Link USB to be used for programming. It should be auto detected by Windows as a USB drive and a ST-Link interface. You should also be able to install the binary by just copying it to this USB drive Here is the correct file location on my github

If this does not work ask the seller of the display for support.

I guess your SD card or reader module is generating a short circuit.

Maybe you used the wrong SD slot module or have bad solder joints?

I think I mount it wrong. I switched sides on the V4 board and now I put the card in and I no longer have the problem. But I'm waiting for the activation key.

Thanx @sortudo1
