I busted my old LCD screen on my Monoprice rebranded Wanhao Duplicator i3 Plus, so I decided to replace it with a new one. I flashed it with 4.0.4. It did get stuck after flashing (just wouldn’t go to the main menu) but I figured since this was my first time using ADVi3++ that was normal. I flashed the mainboard with 4.0.4. Mainboard flash went fine. The LCD showed the “EEEPROM settings not compatible” warning until I disconnected the printer from USB.
I rebooted the printer and the menu loaded up flawlessly. I can touch all the buttons and they light up as if they’ve been pushed, but nothing happens. Temperature monitor on the main screen shows correct data. I re-flashed the LCD and the mainboard with 4.0.4 and the issue persisted. I tried to downgrade the LCD to 4.0.3. It still reads 4.0.4. The screen is not “bricked”, just not doing anything after each button push. I did try the 4.0.5 calibration image (Since I can’t reach calibration normally), and calibration went fine. Those controls responded.
I tried flashing to 4.0.5. Screen still says 4.0.4. I can control the printer via USB fine.
I’m basically out of ideas at this point. Any suggestions? Cable was working fine with old LCD, but if you suspect my cable from mainboard to LCD is bad, can anyone tell me the specifications (pitch, pins) to replace it?
