When you say black screen, there are two options.
1) the video is missing but the backlight still works.
- In a dark room, look for any glow from the backlight of the panel. If you see any glow, the backlight is good, your problem is with the video
2) the video is still there but the backlight has quit.
- Use a strong light or flashlight and point it at the screen to see if you can see any of the image on the screen. If you can see any of the image, then your backlight circuit or the power supply that powers the backlight is faulty |
