firm ware gets corrupted but never erased.
If the turns on but screen is black replace main unit
if the screen turns on but no video replace t-con unit
if no power at all replace power supply.
after replacing the main unit is the screen still does not come on then the inverter is dead. the problem is that RCA did not supply inverters for this model other than if you replaced the LCD panel.
Above is 3 different diag procedures if you need any more help just ask.
