Question:

Why does my TV have a rolling line on the screen? What can I do to fix it?

Answer:

A rolling line on your TV screen is usually caused by a grounding issue. To diagnose and resolve the issue, follow these steps:

Turn on the TV.

Press the SOURCE button to switch inputs.

a. If the line disappears, the problem is with the connected device (e.g., DVD player or cable box). Ensure the device is properly grounded – avoid using 3-prong to 2-prong adapters. Contact the device manufacturer for further assistance if needed.

b. If the line remains, the issue is likely with the TV itself. Check that the TV is properly grounded – do not use 3-prong to 2-prong adapters. Try plugging the TV directly into a wall outlet instead of a surge protector. If the issue still occurs, the TV requires repair. Create an online service request to have the TV fixed.
