But if the Oppo A31 screen flickers, is dim, or doesn’t have a flash, there may be other ways to fix it.
The Oppo A31is a popular smartphone known for its impressive features and affordable price. However, like any electronic device, it can encounter issues over time. One common problem Oppo A31 users face is the backlight not working correctly. In this blog post, we will explore the possible causes of this issue and provide step-by-step instructions on how to fix it.
When there is a problem with the lighting on the Oppo A31, the LCD screen usually doesn’t show anything, so the screen is white. Even though this is the case, the phone may still ring and make other sounds. This indicates that the trouble is with the backlight of the LCD screen and not with the phone’s audio parts.
Common reasons why Oppo A31 backlights don’t work:
1. Damage to the hardware: Physical damage, like drops or bumps, can cause the backlit circuit or other parts to break or become disconnected.
2. Display Connector Problems: If the display connector is loose or broken, it can break the link between the screen and the motherboard. This can cause the backlight to stop working.
3. Faulty Backlight IC: The strength of the backlight is controlled by the backlight IC, which is an integrated circuit. If this part breaks, it could cause problems with the lighting.
4. Software Problems: Sometimes, a software problem or update can cause problems with how the lighting works.
