Google Pixel Unresponsive Black Screen

Along the top edge of the display, several sensors are positioned to report on light levels and distance to a surface (your face, the inside of a pocket, or other).

• Give your screen a good cleaning, especially along the top, where these sensors live. If the sensors are smudged, the phone might think it’s dark out and lower the brightness. To fix this, clean the entire phone screen with a damp microfiber cloth.
  • Use screen cleaner for more stubborn grime.

If you recently repaired your device, make sure the gasket around these sensors if there is one), is properly placed.

In addition to the ambient light sensor, the proximity sensor may also give you hassle. That's the one that tells the display to turn off when you but it up to your face to make or answer a call. Because these can both change screen behavior, they can also generate unwanted behavior.

• Check for liquid damage along the top edge of the phone. Despite the rated water resistance, the earpiece is a common location for liquid entry. Even a small drop can cause damage to these components and they are often near to the speaker opening.

• Unfortunately if this is the issue, the sensors may be mounted directly to the logic board. Other times it will likely be on another small flex cable with other small components.

If your phone is still not responding and has a black screen, try plugging it into a computer. This will provide more insight to your phone’s condition as it will notify you if it detects the phone—letting you know that the phone may be functioning but the screen may not be.

• USB debugging is an optional setting that will give more feedback when the phone is connected to a computer. Unfortunately this setting can only be enabled when your screen is visible and usable.
• Your unresponsive black screen may be caused by a broken screen from a repair attempt or other accidental damage. Look into a replacement screen and follow the associated iFixit guide.
• Display damage may manifest as a visible crack in the glass, but other signs of display damage on an AMOLED display include black blotches, lines or general display anomalies.

The logic board is the hub for most of a Pixel's functionality. Any number of the small components on the board may have failed or become damaged and is a safe assumption of cause if nothing else on this page has worked.

• Check for obvious signs of a board issue—burned or cracked components, liquid residue, corrosion, or bend. If there are signs of liquid, the iPhone Liquid Damage Guide might help.
• Replacing the logic board is often the most practical solution for a DIYer whose board has failed.
• Contrary to popular belief, the board itself can be repaired. However, it requires specialized tools and microsoldering know-how. If you’re curious and want to know more about getting into micro soldering, here’s some good reading and some good watching to get you started.
