The tv is two years old and in fine physical shape. once the light starts flashing it will turn on using the remote but each attempt lasts a shorter period of time until I have to hold the power button on the tv down until it turns off then start over.
That could be a capacitor need to be change.

Unplug the unit for 1 minute, replug and try again. If it doesn't work the power supply is faulted and it needs professional service.

The condition of your TV called power supply overcurrent shutdown that"s why you hear a click. The TV is going into a protection mode to prevent further circuit damage. That's why it will not turn on or not powering up. I would concentrate on the power supply section board. Bad regulation of the incoming voltage could caused this issue although,there is a capacitor across the incoming line and nuetral.Maybe its leak or dry up and cause the problems,change it out with one of identical rating . Although now you are getting into dangerous area,especially if you have no electronic experience background. It could be also be a loose ,crack or cold solder joint,a blown fuse,fusible links or other component .It could be one of several boards.Unfortunately the level of sophistication on these TV make it virtually impossible to diagnose them further without taking them apart and probing around with a multimeter and other tools.This TV is handy enough to take to a repair shop find a good one.You will probably have to pay $75 to $100....
Hope this may help you..

It's a power supply related problem. When it turns itself off, this it called protection mode. The TV automatically turns off to protect other parts form being damaged.
The most common problem is the Power Supply Unit or the Backlight Inverter Board.
You may have to take the TV to a repair shop to find out which one is bad. Paying a repair shop to replace the board for you maybe more than the TV is worth. If you let them diagnose it and you replace the bad circuit board yourself, it would be cheaper.
Here's a place I use to get parts for TVs:

The problem is the repair shop may charge you double or three times of what the part costs at the web site link above. Then, plus labor. I just want to save you money. :)

Backlight invertor is most likely cause of the problem, in rare occasions defective CCFL lamps could cause similar symptoms. Replace defective parts, reset lamp error counter and you good to go.
