Was watching tv and it just turned off
47 inch Panasonic flat screen, turned itself off and will not turn back on. I have to unplug and plug it back in, at that it will turn on but only for about 20 seconds. In order to get it to turn on again, I have to unplug and repeat, but it will not stay on.

Well, first your model number is the 42 inch, but I digress...
I had a similar problem with a Viewsonic 27 inch, with the blinking power light on a failed power-up. It turned out that replacing the power transformer was the ticket. However, as I have the 50 inch Panasonic plasma, I know that the transformer is built into the set itself. I'd still suggest that this is what needs replacing though, as this is different from a set being on but having no picture.
When the tv shuts done does the power light blink? If so what number does it blink? That will tell me which circuit your problem is in. Notice the number of blinks then let me know. Also what is the model number of your set.
Unplug the three red-blue-green plugs nest to the convergence amps. If the unit powers up and stays on the picture will look bad but will confirm that the convergence amps have failed...
Replacing the amps and one or more resistors in the yoke return will restore the set to normal operation..
Use only Sanyo original Ics..
If your unit was blowing fuses you must have had an overload somewhere. Your post is not clear. Does your unit run ten minutes after unplugging and replugging it? If it does then there is still a partial short in it somewhere which causes it to shut down for protection. It could be anywhere. Some detail on what happened prior to the fuse blowing would be helpful for diagnosis. You do not sound like you would have the expertise to troubleshoot this unit. I doubt there could be much wrong with it and the cost should be minimal. Find a reputable repair shop to handle the repair. Good luck.
