Real Pin : Screen always goes off

[needavirus]

Hello, 

 

I've got serious problems with my last pin machine and his Pin2DMD V4-Nucleo144 Shield

The screen always goes off. Like crashed. It can be after a couple of minutes of gameplay, or after 20-30 min. I've noticed it's ALWAYS during an animation, never when the screen is showing score, or even in attract mode... 😕 

Here's what I've do until now : 
- Upgrading Fw > No Change.
- Reflashing SDcard with fresh colorization files (thanks to @slippifishi) > No change.
- Lowering voltage to 4.2Vdc, raising it up to 5.15Vdc > No change.

- Tried Settings Color Storage "Ram' or 'Flash' > No change.

Another note is most of the animations are garbled and mostly the screen crash just after or during it.
But sometimes, the same animations are correctly played... 😕 
I've also noticed : when the screen has crashed, no more Led blinking on the Nucleo board. Just the big power led still lit.

I'm stuck and can't enjoy my game ...  

Any help would be gratefull 🙂 
Many thanks !

>> Update & Solution : 

Simply tried another SdCard (another brand and size). 
Looks like OK for now ! 

Maybe the original card has become out of order ? I don't know. 

There's no brand on it, so probably a bad quality card ... Who knows.

Hope it can help someone a day if he has the same case 😉
