Troubleshooting Display Not Working on Touch Pad for Lippert Level Up System

Question:

The battery went dead on my 5th wheel. After I recharged the battery the screen on the level up system is blank. It lights up when i turn on the system It will auto level and I can raise and lower the the pistons but nothing shows on the display. Any ideas what to do next? Thanks

I reached out to my contact at Lippert and he said there are a couple of things you will want to look at to try and troubleshoot the blank display on your Level Up touch pad. He said to first remove the pad itself from where it's mounted (keeping the wiring in place). At the back of the unit there should be 4 wires; black, green, yellow, and red.

Test each of the wires to make sure they are getting proper voltage. The black wire should be getting 12+ volts of power. The yellow and red wires, which are the communication circuits, should each be getting between 3 and 9 volts. The green wire is the ground wire.

If all of this tests okay then look for the small ribbon wire that's between the board behind the touch pad and the pad itself. Make sure this is still securely connected.

If both of these things look good and you still are getting a blank display my contact said the touch pad is bad and will need to be replaced.

I recently had the same situation (dead battery, power back up and dead screen with hydraulics working), why would the wires and their connections be bad in that situation? Is there in internal fuse in the Lippert controller we can check?
