Hello, You've got two possible causes of this problem- the power supply board, or the inverters. If you want to fix this yourself, you will need to use a multi-meter to test the 24 vdc points on the power supply board (which feeds the inverters) to see if they're in spec. If they ARE- then you replace your inverters to fix the issue. However if that voltage is missing- this means the 24 volt output on the supply has failed- and you will replace the power supply board. There components can be located for replacement by pulling the part numbers off the boards and searching pulled parts sites like: http://www.shopjimmy.com or http://www.tvpartsguy.com

Alternatively if this is not something you're comfortable with, then a shop is going to charge between $200-$250 parts and labor for this repair and can be located at the following link:
