There is a slight flash when I first hit the power button but screen remains black. There is a "click,click" noise that repeats itself every few seconds but the tv never turns on.
I have done some research and found a notorious cap and diode problem with this set. The two 4700uf caps (C14113 and C14115) on the DM1 power board (the board to the left of the sat. box when you look at the set from the back) are under rated and will eventually fail. When these caps fail they tend to take out diode CR14105. This may be your problem. If it is, you can replace the caps with 4700uf 25V 105c and the same as original diode.
sounds like the Power Transformer to me, usually accompanied by a high pitch (almost inaudiable whine) and sparks arcing.
This needs a professional repair..
