My T.V turned off by itself and would not turn back on for awhile. Now
when I plug it in all it does is make a high pitched clicking sound. In other
submissions it has been said that it could be the flyback trransformer. If it was this could I do this myself and if so where can I get one?

It appears that there may have been a power surge or something that damaged the electronics of your set and cause it to work the way it is now. You might want to try replacing the power supply since it is the first area that would have a surge go through it and sustain the damage.
I had a similar problem with my Phillips 42 in. LCD HD TV.
Here's the problem. The Power Supply Board. I opened my TV
up(warranty was up of course) and found several bad capacitors.
Phillips and several other companies were sold capacitors that although
were highly rated failed within 5 years because of a lack of
preservatives. All sorts of electronic equipment is now being effected
due to these defective capacitors.
1. Take it in and have it fixed
2. Open it up, check the board for faulty capacitors(bulged or leaking) Buy a new Power supply board and install it.
3. Remove PSB, remove faulty capacitors and replace with compatible new ones.
try unplugging the 3 wire plugs for the convergence yokes and try powering up the set. if it comes on you will need convergence ICs if it doesnt you will need a deflection board. let me know what you discover as I can help you with either problem
Just keep smack'in it around, it works for me.
It is the 'protection overload circuit' taking over and shutting the TV set off. This is because it detected a short or near-short circuit somewhere. Most common is high voltage, deflection amplifiers and main power supply. It's pretty much a common fix for an experienced tv repairman. It might set me back in the ballpark of $200 - $300.
