=== ***1. Check Cable Connections*** ===
* If you're using an external device (like a set-top box or gaming console), unplug and reconnect the HDMI or AV cables.
* Try using a different HDMI port or cable to rule out a connection issue.
=== ***2. Perform a Power Reset*** ===
* Turn off the TV and unplug it from the power source.
* Press and hold the ***power button on the TV*** (not the remote) for ***30 seconds***.
* Wait a few minutes, then plug the TV back in and turn it on.
=== ***3. Inspect for Physical Damage*** ===
* If the screen has ***cracks or pressure marks***, the panel may be damaged, requiring replacement.
=== ***4. Test the T-Con Board (If You Can Open the TV)*** ===
* If the lines appear ***consistently across all inputs and the menu***, the T-Con board or ribbon cables may be faulty.
* Try reseating the ribbon cables that connect the display to the motherboard.
=== ***5. Contact Support If Needed*** ===
* If none of these steps work, the panel or internal components may need professional repair or replacement.
