TV Has Sound but No Picture: How to Check for a Backlight Fault
Quick answer

If you hear sound but the screen is dark, shine a torch close to the screen. A faint picture in the lit area means the backlight has failed, which needs a technician. First try another input, unplug HDMI devices, do a power reset and check picture settings and any 'screen off' mode.
