Samsung TV no sound no picture backlight on and off

Check voltage at the power board. After 120 volts enter the TV, there is fuse then a small high voltage transformer, then a 100 uf rated at 450 volts capacitor. There should be 390 volts DC at the capacitor. Without this 390 volts the TV will shut down.

I have a ln-s4092d that had the same problem after a little more than a year of service. Replacing the main board seemed to fix the problem. But about a year later, the same problem has reappeared.
