The power supply will sense if the set is 'drawing' too much current and switch itself off. This could be the case here. The power supply board may eventually go completely bad.

Mine was doing that then it quit even turning on too so I replaced the 4 Capacitors today on the power supply board that had bulged up on the top 3 had split open they where on the top right corner of the board where the ribbon jumps from the power board to the main board with ones from Jameco Part Number 606521 they worked perfect but make sure you put them in with the correct polarity easy to do just keep an eye on it. Very simple repair and took me about 30 min to take itapart solder on the new ones and put it back together all for under $10.

This is the capicator $1.50. You have to take off the back, sauter off the capicator (you'll see it because it is poking out) and sauter on the new one. I found the fix on this web-site.

There is a problem with the power supply in your TV. The regulator switch is causing teh clicking sound you hear. In order to fix it, you will need to replace the power supply. This is done by taking off the back cover of the TV, locating the power supply which is usually a yellow board that will have many high voltage capicators on it and replacing it with a new one.
