The 2 long boards call the LCD inverter boards are dead.These 2 long LCD inverter boards are dead,must be replaced.These 2 long LCD inverter boards help the LCD screen to have a backlight to have a picture.Tries websites like Shopjimmy.com,Ebay.com to buy those 2 long LCD inverter boards for the replacement.

Since you have no picture or sound, then more likely to be power supply or main board problem, so check the power supply output voltages first, shorted out backlight inverter board will also cause the power supply to shutdown also, so try disconnecting the inverter from the power supply board to see if the power supply will start back up and at least get the sound back.
