hi, I'm using an anycubic i3 mega (so a trigorilla 2560 board), with a YB2004D as a display/sd module with marlin firmware

the display should be a clone of the "REPRAP_DISCOUNT_SMART_CONTROLLER"
[here]( ) you can see how the board looks like

it looks like [this]( ) , it won't display anything

[here](https://wetransfer.com/downloads/8c649aba2d31ac7c81d0b4c7b0aef7eb20211116074849/b9ff23) you can find the marlin build under the zip

the issue is not the display, previously it did work

ps: I don't think that's the right forum where to ask, but I'm not finding any right forum that's active
