Samsung Phone Screen Lines: Fixing Display Issues

Is your Samsung phone screen displaying colored or blank lines? This can be a frustrating and annoying problem, but it can often be fixed with a few simple steps.

Solutions to Samsung Phone Screen Lines

Here are some solutions to fix your Samsung phone screen lines:

1. Update your phone and all apps.
   It is rare for a smartphone to develop issues producing an image because of a software issue, but it is certainly possible. Bugs in apps or the operating system could cause this sort of problem. The location for System Update varies by Android version. To find it on your phone, skim the main settings menu or do a settings search.

2. Reseat all display cables.
   The connection between the board and the display may not be solid, especially after a hefty drop or after repair. Missing signals can lead to missing data on the display.
   
3. Replace the display.
   Although most display failures seem apparent, this is not always the case without visible damage. Display failures can occur due to manufacturing faults or imperceptible damage.
   
4. Replace the affected cable (or display assembly).
   Display information is transmitted through several electrical lines, both from the screen to the system board and on the display itself. Damage to specific lines can lead to missing data about parts of the display, which can manifest as colored or blank lines.
   
5. Replace the motherboard.
   The motherboard is the hub for most of a smartphone’s functionality. Any small components on the board may have failed or become damaged. It is a safe assumption of cause if nothing else on this page has worked.
