Blank screen after update firmware


Topic starter



I've trying update the firmware for my Ender3 Pro with V4.2.7 card with this firmware of your site


but nothing appears on the screen and I can't do anything.

How do i solve this problem ?


Many thanks

@ovrancken I assume that the black screen happened after you uploaded the new firmware. you can try the newest one below. 

4.2.7V-Ender-3 Pro-32bit Mainboard-Marlin2.0.1- V1.3.1- BLTouch-TMC2225


I don't see this file referenced...  I see this one with an adapter board... which I don't have.  nor do I have a filament detector...    Am I missing something?


the firmware changed names. You need to tell me the problems so I can help you in a way.
