Mac has no display.
Why is my Mac display not coming on?
There are various reasons why this can happen.
1. Backlight is not coming on however when you shine a flashlight you can see the desktop icons and this can be attributed to the malfunction of the backlight circuit.
2. Liquid damage due to the chip on the logic board that converts the power from the battery to the correct voltage for the backlight getting wet. This can happen if you have spilled something on your Mac or even put it on a wet surface.
3. Impact damage that can show a completely extinguished screen pointing to a blown fuse and the ribbon connection inside the cover. The inverter chip is usually burned and it involves the logic board.
4. Sometimes corrupt information on the startup disk can result in a black screen on your Mac. You need to force your Mac to run diagnostics on the disk by booting it in safe mode by powering up or restarting your Mac.
5. After updating your Mac to the latest macOS you see a white, gray, or black screen that can be caused by some technical issues eg lack of memory.
