jmcdonald sounds like your inverter or your power board is on the fritz. Check in a darkened room with a flashlight beam angled against the screen if you can make out any shadows etc. If you take the back off and take a couple images and post those with your question, we might get you to test some voltages to see if it is the power board not supplying proper voltages to the inverter or if it is the inverter. Use this guide for that.
You should have another board in there. Something like this
That's the inverter board.
You also want to take a multimeter and test the output on the connector marked with the red arrow.
