How to Fix TECNO Screen Display Lines and Stripes

Display lines and stripes appearing on your TECNO screen indicate a hardware problem with the LCD panel or display connector. These visual artifacts significantly impact usability and indicate that professional repair may be necessary. Before seeking service, try these troubleshooting steps to rule out software causes.

Steps to Fix TECNO Screen Display Lines

Restart your device: press and hold the power button for 10 seconds, wait for it to power off, then press again to restart.
Check recent app installations: go to Settings > Apps > Manage Apps, review recent apps, and uninstall any suspicious ones installed before the issue appeared.
Clear system cache: turn off your phone, hold Power + Volume Down to enter Recovery, select "Wipe Cache Partition," and confirm.
Update system software: go to Settings > About Phone > System Updates, tap "Check for Updates," and install if available.
Factory reset as last resort: backup your data first, then go to Settings > System > Reset Options > Erase All Data, enter PIN, and confirm.

🤔Note:

Display lines appearing in the same location consistently usually indicate a hardware defect rather than a software issue. If lines don't change after restart and software updates, the LCD panel likely needs professional replacement. Contact TECNO service center for warranty evaluation.
