The heart of the board. The schematic shows 128 pins grouped into functions:
Key clue from schematic: The TSUMV59 requires a 24MHz crystal (Y1) between pins 14 (XIN) and 15 (XOUT). No oscillation → no boot. Measure with an oscilloscope or test by replacing Y1. t.vst59.031 schematic diagram
The most confusing part for beginners is the LVDS connector (CN2). The schematic shows a 30-pin or 40-pin header.
Pins 5-10: Ground.
Pins 11-30: LVDS differential pairs (A0-, A0+, A1-, A1+, A2-, A2+, CLK-, CLK+; then B0-.. for dual-channel panels).
