Question about Televison & Video
Sounds like you have a back light problem. To verify this, turn on the set, dim the lights in the room, and shine a bright flash light on the screen. If you see the faint picture on the screen, you have a back light problem. You could either have a shorted inverter that is pulling down the 24vdc line, a blown CCFL back lamp, a high voltage short (arcing) from one of the inverter outputs, or a faulty 24vdc power supply

the clicking sound is the result of a faulty power supply, some capacitors(blown heads) on the power supply for the output voltage rail of the mains board need to be replaced.

I just fixed this very same problem. It is the capacitors are the problem. However, I think that if you have some minimal skills with soldering, you can fix this yourself. You just need to take out the system board, then the power supply parts are on the top right. The bad capacitor(s) will be bulging at the top and possibly have some brown stuff coming out. The ones that go bad are 1000microfarad, 10V, however you can replace them with higher voltage. I got 35V caps from radio shack for 1.59 each. You just need to solder out the bad ones and then put the new ones in and solder. Remember that the negative end goes on the side with the bold black part of the circle on the system board. Then just cut off the extra ends of the capacitors. If you are capable of doing this yourself, you will spend at most 6 dollars instead of however much a technician costs.

if you can do soldering work, replace two 1000uF10v bulging capacitor with 1000uF 16v or 25v in powersupply board. you will save $200.
