What is the model number of your LCD?
As mentioned by mistersony, there might be some capacitors loosing their dielectric capability and that is why you need to unplug it to restore its functionality.
I've repair a few hundreds of these power supplies, let me know if you need further assistance.

Looks like there is a short circuit or broken solder somewhere on the board(s) causing the system to go into a protect mode. I would check for these first.

PS - if you have no prior experience with TV repairs, I'd recommend leaving this to a professional, as there are voltages inside that can KILL, even when unplugged.

It is possible you have one or more leaky capacitors in the power supply that will not allow the switching power supply to start. Examine the power supply for any signs of swollen capacitors or capacitors leaking onto the power supply board

    The caps that are bad are usually tall cylindrical parts with numbers like "3300 uFD 50v" on them

AKAI 32" LCD HDTV WILL NOT TURN ON


The only solution at this point would be to get the power supply repair since new boards are not longer being manufactured. In about 95% of the time if the LCD doesn't power up or turns OFF by itself or need to be unplug for some time to make work again; those are the symptoms of a dying or defective power supply.
I service these power supplies, for more info write to jah2mil@hotmail.com

The power supply most likely failed on your LCD.
How old is your LCD?
