Troubleshooting Solutions
Performing a Picture Test

Repairing Faulty Components
If vertical lines persist on your Samsung TV screen after performing various checks and resets, it could indicate a hardware malfunction. Common areas that might need attention include the T-Con board, main board, or the panel.
