BOTH OF THE STK-392-560 convergence chips need to be replaced; there are also fuses on the power board that protect them--do not look like fuses; if you need photos of the place where the chips are and the fuses, let me know.
Repair takes about a hour and parts if purchased on EBAY will be under 25 dollars.
There doesn't happen to be a speaker nearby does there? I've seen this a lot with center channel surround sound speakers. It goes like this because of the magnet in the speaker. Try moving the speaker if there was one (or anything else near the TV that may have a magnetic field).
Then, every time after you turn your tv on it should get slightly better thanks to the built-in degaussing coil in your tv.
If not, find a TV/Appliance repair man near you, and he will have what's called a De-gausser and will probably charge around $30 to use it on your tv.
You'll be watching 2D TV again in no-time!! ;-)
I own the same model of tv and have owned it for over 1.5 years. I moved with it twice. I had this problem about a month ago. On both vertical sides the screen became very fuzzy, yet the center remained clear. When turning the tv off and on I also noticed very wierd red, green, and blue lines streaming across the screen before the picture comes up or after it fades. I found no solution or cause to the problem. But I had two "long-boy" speakers from my panisonic 5.1 surround sound system setup right next the tv on either side. I set the center channel on top of the tv with the receiver on the shelf below. I thought well maybe some how the speakers were cause some sort problem in the tv. I moved the side "long-boy" speakers from directly next to the tv to about 6" away and removed the center speaker from the top of the tv. After several days of normal use of this configuration, the tv turned like normal and the fuzzy edges were gone. The symptoms lasted for around two weeks, and the several days after I moved my speakers. My only guess is that without a deguassing feature, it took several days for the magnitism to return to normal after repositioning my speakers.
Best Educated guess would be your Flyback transformer is failing. Not something you can replace at home and the value of the part may exceed the replacement value of the set by the time labour and part are factored together. DO Not look to replace this part yourself as this part inside the set as it has a high voltage that can be lethal. Output voltage can be around 50,000
