I have a screen from a cd player/ radio that I would like to use for my 3D printer that uses an arduino mega and ramps 1.4. I found documentation for the board and screen. (Philips BTM630/05 Service Manual (Page 23 of 33) | ManualsLib). I've read a few other post about reusing screens so I understand that this maybe not worth the effort especial since I am new to this. However, I'm hopeful since I have the PCB. Is this viable? Can someone point me in the right direction?
According to the manual you linked to, the display board uses an HT1622 display controller. A quick search reveals a github library that you could try:
EDIT: I forget to say that the manual also shows the schematic of the display board and the connector pinout.
