If it's LED or LCD then it's backlights-- just shine flashlight on screen at an angle and see if you can see any movement or bring up menu display and with a flashlight you should be able to see it---as stated above---
Symptom: No picture on screen but LCD TV still has sound.
Solutions: The problem is cause by defective inverter. Replacing inverter will solve the problem---ou cannot see anything at all then it's T-Con board--

Playback movie pictures or sound
Movie pictures can be played back with the camera, but not sound. However, when the camera is connected to a TV, both movie pictures and sound can be played back. For playing back movie pictures or sound on a PC, the QuickTime™ 4 is required.
