Is the issue the same on all channels?4. Press the Home button (looks like a house), select Source, and choose another input source. Is the issue the same on all sources?5. If the same problem persists, run a diagnostic test. (Home > Settings > Support > Device Care > Self Diagnosis > Picture Test)6.
