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.

Installation
Simply plug the board onto the EXP3 Header on your LCD and then plug the LCD cable into our board as shown below. No firmware changes are needed.

I tried the board, but it did not work, I sent you two emails about it. Could not tell it did anything. Thanks
Hi there Frank, that was because your control board had another issue – we sent this out as a test to you to see if it would fix anything. I remember we sent that to you to test. However, we did later find out the issue with the Ender 3 S1 Boards that was causing the LCD corruption you were getting.
