Selection knob not working?

Post by ericksonla » Wed Jan 16, 2019 1:50 pm

We've got a Taz 4 that we just pulled out of storage. The selection knob can physically turn, but the GLCD doesn't respond to rotations. If we push the button, it will change screens. But if the screen is a menu, turning the knob doesn't move the cursor to other menu options. Perhaps relatedly, it seems to say no SD card, when there is in fact one in there.

Any ideas whats going on? We've moved it quite a bunch which may have jostled something loose, should I pull it apart and check if there's a loose solder joint? Or is there another good option?

Thanks!

You will see a small ~8 pin connector on the control board from the LCD, that is what the knob & SD card communicate through to the RAMBo. I do not remember which connector on the back of the LCD that is also.
I will express my CRAZY ideas at any time! So you have been warned. None of my opinions are Lulzbots and can be wrong at any second.
