I have researched this problem and it is so common we that own this piece of junk ought to form a class action suit and sue. It is caused by a bad part or bad connections to a part called a backlight inverter. It seems the LCD needs a higher voltage than supplied by the 12vdc power pack so this part re-chops the DC voltage to generate the LCD requirement.
The date of manufacture is on the back of these TVs and all the problems seem to be from those made in 2006 to 2008

lcd sets use florescent tubes to light the display and, a ballast to power the tubes just like the lights in an office ceiling.
the tubes are called cold cathodes and, the ballasts are called inverter boards. replace your inverter circuit board it connects by wires to the cold cathodes so; isn't hard to find.

I am having the same issue, I think the best solution is to replace the inverter slave and master boards. These are the circuits that controls the backlight and causes the flickering when they are malfuctioning.

Problem with flickering is in the board that is mounted to the back of the lcd screen. Part is only available in China.
Board will either need replacing or repairing (if it is repairable? Not all are)
I repair lcd monitors on ebay and just repaired one of these boards.

Sounds like you have an LCD tv with backlight problems. Check power board for domed capacitors and replace them. next check connections on the inverter boards. they are on the sides or just one side. Becareful there is high voltage output from these boards. If the cable from inverter board is not good to the screen you can get a strobing. the inverter boards may need replaced. or cales to screen may be bad. The panel also could be bad.
