Not really a new subject but I haven't been able to find a fix and havent seen anything exactly like what I have going on. So here goes. I have the Geeetech Acrylic I3 Pro B machine.
This was purchased in July of 2015 through Ebay as I recall.
According to My parts book I am running a GT2560 Control board with an LCD2004 Display, although the board reads 2004A, if that makes a difference.
Ever since I've owned it the display doesn't work right. Ive always just kept it attached to my laptop so I didn't really need it. Now my husband is using it and wants it to read correctly.
Anything new to try?
Thank you
Cheryl

Re: LCD Black Squares
Hello, you can exchange the cables between the LCD and SD card. It may be a bad cable. If it still doesn't work, you may need to replace the screen.
Re: LCD Black Squares
Thank you for your reply. We have tried changing the cables. So i guess ill look into a new board.
I was hoping it was a setting in the firmware but i haven't found anything other than removing the // in the one line. unfortunately they were already removed so that wasn't it. tried adding them in but that didn't change anything either.
