pin2dmd XL display issues

[Crrispy]

Hello,

I just installed a brand new pin2dmd XL in my Baywatch. I have lots of pixels noise on the display, quite unbearable. Also colors are sometimes right, sometimes wrong, Sonic in attract mode is green instead of blue, etc... Here are 2 videos showing the issues:

Firmware was 3.15, upgraded to 3.17, no change. I have tried 2 different SD cards, no change. "Pixel noise" is already here without sd card anyway.

Did someone already see this?

Thanks.

Check your power supply. How are you powering the PIN2DMD?

problem fixed by shorting the ribbon cables.

...and by upgrading the firmware ? Thanks for the great support, happened elsewhere though since my post here took several days to be approved.

Your post appears empty, did you delete its content? From the preview I got in the mail notification, you were asking if an external power supply would improve the pixels noise? Well first it would need to be a 12V power, not 5V, and I also had tried with an external one before shortening the ribbons, it hadn't changed anything.
