ANSWERS:

tammyradermacher could be an issue with the power board as well as the backlight. We need to know what model this is and what you have tried. First off. Unplug all video inputs and other devices attached to your TV. Then unplug the TV. Hold the power button down for 30-0 sec. Then plug the TV back in with one video source only. Preferably a local device like a DVD, BR or Game Console. Then turn it on. Lett us know what you got.
