SOURCE: convergence problem???
I am a TV tech and have had experience with this type of problem on many sets...So Far the only trouble is the 2 output ic's stk392-110 which should be replaced with the upgrade stk392-180..All three Color Amps are within these ic's for both horizontal and vertical convergence. Sometimes a resistor or two will burn out as well because of the short in these ic's. Be sure to be extrremely careful unsoldering and soldering and use good heat sink compound and fasten securely to the heatsink metal. Manual convergence calibration may be necessary after the ic's are replaced. First try Touch Focus after the ic's have been Properly replaced. This repair should be done by competent personnel and takes about 3 hours because of dis-assembly and re-assembly time. I am writing this because i have seen on this site mis-leading info. i come to these sites myself to verify part numbers and to see if there have been additional complications such as complete shut-down.

Go on line and get an original Sanyo STK 393-110. Next, restore the blue centering rings back to where they were before you moved them. Look at the paint marks on the rings for reference if you are not sure. Replace the IC and check the resistors nearby for signs of overheating and proper value. Also check the fuses that supply the 24v to the IC. The service manual will show you the fuse location and give you the resistor values in the blue horizontal and vertical circuit. Checklist: You need a de-soldering tool or a good quality Dry Wick. Have a small tube of heat sink compound to liberally apply to the new chip. The hardest part will be lining up the double rowed pins on the chip and getting them to seat at the same time. Next, go to the convergence menu and follow the instructions. Good luck! PS you might want to remove the chassis from the cabinet to make it easier. Be careful to unplug the speaker plug and untwist the wire ties from the cabinet. Be very careful, this job is not designed for beginners.

There is an option in the user menu on the tv. Using either the remote or control panel on the front of the tv, press MENU then select SETUP. After you choose SETUP go to the 3rd column with the 3 icons. Here you can adjust the red or blue color or reset the convergence back to factory default.
After a few years the set will begin to show increasing problems with the convergence settings. When you can no longer adjust either red or blue horizontally or vertically an IC replacement will be needed. Your set uses (1) SANYO stk393-110 and you want to make sure it's SANYO and not a knock off brand as those usually fail prematurely.

The convergence IC's need change, or you need a new convergence board.
You can get The IC's atwww.mcmelectronics.com or a new convergence board at www.partstore.com
