| Symptom | Likely Cause | Datasheet Section to Revisit | |---------|--------------|-------------------------------| | White screen, no image | Missing VGH/VGL voltage | Charge pump circuit (Figure 9) | | Flickering lines | Incorrect HSYNC/VSYNC timing | AC Timing Characteristics (Table 12) | | Colors are inverted | Wrong MADCTL setting | Command 0x36 description | | Display fades over time | VCOM voltage drift | VCOM adjustment register (0x44) | | No response to SPI | IM[2:0] pins misconfigured | Interface Mode Selection (Table 4) | Use the TE (Tearing Effect) pin. As per the datasheet, a TE pulse indicates the driver is actively refreshing. If TE is stuck high or low, your initialization failed.
