ANSWERS:

@daveb first check to see if the backlight is just not working. In a darken(ed) room, angle a flashlight beam against the TV screen (TV on of course) and see if you can make out any shapes or shadows. If so it's your backlight. If it does not you are most likely having power board issues. Post some good images of all your TV's boards with your question. Use this guide for that. It will allow us to see what you see. To further diagnose you will also have to have at least a multimeter. Check your boards for bulging or leaking caps.
