What should you check?
- 01
Open the TV’s own menu
If the menu works, check the input source, cable or connected player before assuming the panel is broken.
- 02
Check sound and picture separately
Note whether sound is still playing and whether another input works. A persistent blank panel needs professional testing.
When should you seek professional repair?
If the symptom persists or you suspect physical damage, get a model-specific diagnosis and a written cost estimate. Avoid changing important settings or erasing data without a backup.
