hi Traci.
The online references, manuals, etc, refer to a back light, but then generally start pointing toward the backlight inverter, which is the power hook-up for the light source. They can be found on eBay
toshiba 65 ht 2 backlight inverter . Videos such as this one talk about replacing such a unit in a Toshiba, along with diagnosing what exactly has failed between power and the picture screen that's gone black.
Hope this helps!
