LCD Reseting and non navigable!

Post by WiscoMudder »

I have been having this issue for since the beginning. I've gotten 2 replacement LCD Screen controllers.
I can't navigate with white knob it will reset the screen, I can click in a few but can't go further. I'm told its a wiring issue on my end however my cheap eBay Prusa i3 screen hooks up and works flawlessly on my Rostock Max V3. Other then that my machine works fairly well. Considering its the dual extrusion set ups and randomly switches materials by itself.

Any idea's?

The adapter board might be off by one pin to the left or right.

I will check this, this evening. Its possible but If 1 cheaper eBay board works why wouldn't a similar one?

I made sure the adapter board was seated correctly, all fuses are fine, I refreshed back to single extrusion and my extruders don't work. Even after unplugging the E1 motor. LCD behaves the same way.

The boards look fine and no visible since of damage with a 10x magnifier.

Seriously puzzled.

I even tried a board much like it off of amazon. Same results.

Make sure the red wire points to the left as you look at the back of the screen. Sometimes the connector gets put on backwards.
Never do anything you don't want to have to explain to the paramedics.

So far the wiring seems to be correct. I even ordered a replacement screen from e-bay and behaves the same way.

If I switch the wires around or flip positions nothing works at all on the screens. Is there anyway to test the board?
