The tv power supply board it is shorted and dead.That the board where the tv power a/c cord plug into it.Tries websites like Shojimmy.com,Ebay.com to buy a whole new refurbish tv power supply board for the replacement.
You will either have a fault with the inverter board which drives the backlights or a faulty backlight in the screen. If the problem is a backlight then a replacement screen is the only cure. One or the other is breaking down after it has been opn for a certain period of time, have an engineer call out & check with a tester if it is a screen problem.
we had a similar problem on our 40 inch samsung , the screen went black but we could still hear sound on ours it turned out to be the main board not the inverter like some people liked to think thanks

do you have heater voltage because if you are hearing high voltage you may need to replace a resistor and capacitor in the 200v circuit or you could possibly have a anode not seated right arcing on somthing or a bad flyback
