LCD BIST
LCD BIST (Built‑In Self Test) helps you determine if a display problem is caused by the LCD or some other part. The test may displays different colors and text on the screen and if you do not notice the problem during the test then the issue lies outside of the LCD.
NOTE Peripherals may have diagnostics specific to them. For more information, see the documentation shipped along with your peripheral.
