so i put in a new mother board in my A20M and now the screen is not working it turns on to the blue screen and thats it any ideas????

Hi, you mean that when you replace the motherboard,
The printer's screen is only backlit.
You can try to reconnect the screen cable.
When the screen line is not in good contact, the screen will not work properly.
In order to solve the problem better,
You can describe the problem in detail or provide a specific video.

yes i put in a new motherboard my old one was dead and now with the new board my screen only shows a blue screen and nothing else no temps no nothing

Have you tried to reconnect the screen cable?
Poor contact can cause this to happen
