Issue Details
Due to design of the E3 Mini/Turbo, V4.2.2, and V4.2.7 boards suffer from EMI on the LCD lines. This presents itself as if the LCD button is being pressed repeatedly or the feedrate on the LCD (the 100% changing) changing on its own. This is most common on the Ender 5 series machines.
This is not a firmware issue; this is an issue with the board itself. Help Center Article with more details: SKR E3 Mini, SKR E3 Turbo, Creality V4.2.2, and V4.2.7 LCD EMI Issue – TH3D Studio LLC

Question
Sds5150 –
I have an Ender 5 pro with a 1.1.5 board melzi board and stock LCD. I appear to be having a noise issue. I had moved the main panel to the back of the machine to avoid flipping it upside down to get to components. Previously, I had seen this issue, but not as often. I purchased a longer cable to reach the LCD display from the back of the machine. When the machine is running the screen will become unreadable with jumbled up characters and shapes that change. If the machine sits idle, this doesn’t appear to happen. A power cycle also resets the issue. I have attempted to route the cables away from the heater/stepper wires, but this still seems to occur. My question is, if this EMI filter is a possible solution for these components, as I see it is specifically listed for 4.2.2 and 4.2.7? Thanks!!

We’ve had that issue with our Ender 6 in the print farm. Sadly, this EMI filter will not fix the LCD corruption issue. In our case, the issue was due to bad grounding on the printer PSU. Once we fixed that the problem went away.
