Well, any LCD panel requires 2 things to work: a controller and a power-supply/inverter specifically designed to light up the display LEDs. In consumer grade displays, these components can be 3 different things (ie controller, psu, and inverter) and are fairly cheap to replace. You can generally find them on eBay. The only way to really damage an LCD panel is by dropping it and if that is not the case with your display, you can bring it back to life by identifying which of the 3 components might be bad and replacing it. Don't be scared to get surgical with your display. In the end, you will most likely learn more than you will regret.
