Question:

How to fix rolling lines appearing on the HDMI video input?

Answer:

Replace your HDMI cable with another HDMI cable.

If replacing the HDMI cable does not resolve the issue, test the device on another TV.

If the rolling line persists on the second TV, contact the device manufacturer for further assistance.

If the rolling line appears only on your TV, the TV requires servicing.
