Our set turns itself off by itself. Prior to this happening, it goes to a green screen. It usually happens after the set has been on for a couple of hours. We bought the set in April, 2004 and the warrantly has now expired. The longer we keep the set on, the more it turns itself off. Is this a tuner, on/off problem or the tube? Any estimates for repair?

Turning your tv off did not cause this issue, so don't blame yourself for that. A 6 or 7 blink shutdown is because one of the two switch mode power supply control ic's have failed. the part number on them is mcz3001. They are located on the "D" baord, i don't recommend replacing this yourself because even with a tv unplugged from the wall high voltages still exist in the set.
A repairman may preform one of the two following things, he may change the whole D board or he may replace the individual components. The repair will cost around $200 if they replace the components, and if they replace the board it will cost more.

phillips has the same problem but if your tv actually turns on it could be a short or just a fuse sonys a better tv than phillips should be an easy fix call a repir guy going price for that problem is 75.00 dont pay any more than that. the economy is bad everyone needs the work be smart. make sure if you say yes to the work that the repair guy will waive the consultaion cost of usually 35 to 75 dollars, if you chose to have the work done.

Thanks for using FixYa. If its flashing continuously and you are unable to count the no# of blinks then the issue is with the bulb going bad and should be replaced. Please do accept the solution if the issue is resolved or post a comment for further assistance.

There's a good chance you have failing electrolytic capacitors either in the power section, and the clicking is the protection relay kicking out.
Any caps in this or other sections that look bulged at the top, or bulged/leaking at the bottom need to be replaced.
If you repeatedly turn it off and on, eventually it'll probably stay on, but every time you turn it off, the TV will get harder and harder to start up until one day it just won't.
Sometimes you have to do the opposite to start it up and unplug it for some time and then try again.
If you aren't tech savvy, don't worry, read the rest of this solution and watch the videos.
If you are handy with a soldering iron and can identify the power supply and inverter / FM section for the backlights, an inexpensive handful of capacitors will likely fix you right up.
Match the capacitance on the capacitors. Go over voltage if you can, and still have them fit.
IE - it's not a bad idea to replace a 10V cap with a 16V or 25V or even a 50V, but don't replace a 680uF cap with a 500uF or a 1000uF (unless you are positive it's only doing ripple filtering, and even then, you should go OVER, not under the uF rating).
Most of the caps that go are 10V 1000uF or 3300uF.
I found some great videos of the procedure (for many Samsungs with the same issue) on youtube.
As you can see, this issue spans plasma TVs, as well as large and small LCD TVs and monitors.
The parts are cheap, and skill required is minimal.
