While the LAE801P Rev 2.0 is a remarkable device, its schematic diagram can be complex and challenging to work with. Common issues include:
If you are evaluating or creating an improved version, ensure these sections are present:
A "better" schematic is not just about the correct connections; it's about creating a robust and readable design that facilitates troubleshooting and ensures long-term reliability. Here is a structured approach to developing a superior schematic for your LA-801FP display. Elias opened the attachment

The Revision 19 schematic Elias had been working from was functional, but it was a victim of "digital clutter." The grounding paths were ambiguous, drawn in a way that suggested the layout engineer had struggled to fit the traces onto the board. The signal lines for the current sensing op-amps ran parallel to the high-voltage switching lines—a classic recipe for noise injection. In the PDF, the lines were drawn on top of each other, obscuring the interference.
