SOURCE: Push Power button, green light goes on for a few seconds then nothing....
I would suggest taking a look at the power module if that can be replaced. The Fuse blowing may have only been the beginning of the problem. Any recent issues with under or over voltage in your home?
SOURCE: Television keeps turning itself off.
There are two integrated circuits called convergence amplifiers , they need to be replaced. this is a common failure on this model. the cost to replace with parts is around 250.00 dls depending on the tech. if you need more help let know thanks

most of the time the convergance ic go bad:
but try this:
The 3 flashes of the led when you plug the unit in is the
microprocessor initializing.
This unit has an error code diagnostics.
On the front panel of the unit press and hold the INPUT and MENU
buttons at the same time and hold them down for about 5 or 6 seconds.
The unit should activate it's error code mode.
The led will flash count the number of flashes. It will then pause for
1/2 or 1 second. The led will flash again count the number of flashes.
The unit will repeate this for about 5 or 6 times.
You now have the two digit error code. The first time the led flashed
is the first number of the error code, the next time the led flashed is
the last number of the error code.
12 ----------- indicates no error
21 ------------- X-Ray Protect circuit
22 ------------ Short Protect circuit
23 ------------- Horizontal Deflection failure
24 ------------- Vertical Deflection failure
Most units give a error code "22" short protect circuit. If so check:
Q5A00
C557
If Q5A00 check bad there are other parts that have to be checked or
replaced.
If you are able to do above call a tech to service the unit

You should call a good TV Tech. This problem cannot be solved by a consumer. The one thing you might try is to unplug it from the wall for a few minutes and then try it again.
