When you hit the power button the green light comes on for two or three seconds then it clicks and goes off
This issue is almost always caused by a faulty Convergence IC inside your TV. These chips heat up and can become damaged over time. The most common cause I have seen for the picture distortion is the heat of the Convergence IC weakening the solder connection to the TV circuit board. If you look on various messages board you will see people rigging wooden dowels and other items to apply pressure to the chips in order to correct their picture issue. This works because when the solder joint is weakened the chip becomes loose and vibrations or pressure will cause it to work or not work correctly. Aside from all that information the correct fix is to have the IC chips replaces on your TV.
The solutions for this issue are as follows:
1. located a tv repair shop that will replace the parts for you. I had the same issue with my 65" Tv and the quote was $350 for the labor and parts.
2. You can ordered the IC replacements yourself online by going to google and looking up a reseller of the STK392-110 Convergence IC that is inside your model TV. You will need 2 of them and they cost around $6 each. If you have the soldering skills to remove the old chips and install the new ones this is by far the most cost effective route. It is a fairly simple process and guides can be found online.

I have a WS73411 that just started to do the same thing. You hit the power button and the green "on" button stays lit for 3-4 sseconds then powers off. We continued to hit the on button repeatedly and the TV came on...only to have the picture be very fuzzy with red and green colors mostly...??? Anybody?
