Replace STK convergence IC's w/OEM or better parts.Senior tech soldering ability needed. Ex==Steel jumper wires feeding b+ to conv. IC's need resolder to prevent call-back.Also, best re-alignment done in service mode==consult service literature.
SOURCE: The auto convergence no longer works. The crosses
The common covergence problem with these sets is a blown solder in fuse beside the flyback transformer. It blows due to bad solder connections on the transformer itself.

You need to get to the service menu--it's been 4 years so go to AVSforum.com to turn off the different guns and get the better pattern.
At your risk:
To get into Service mode:
1. Turn your TV on.
2. For X81 or earlier series: Press MUTE on your remote and release.
2. For H80/H81/HX81 series: Press MUTE on your remote and release two times ("Mute" on-screen)
3. Press down MUTE on your remote again and hold. While holding, press the MENU button on your TV set's front panel. 4. Release both buttons.
5. An "S" should appear on your screen. Press MENU again on your TV.
6. Now you're in service mode. Channel Up/Dn - Scrolls through Parameters and Volume Up/Dn - Changes Parameter Value
To get into convergence mode:
Get into Service mode, then
Hit '7' to bring up the convergence grid.
Buttons 100, 0, and ENT control which gun you want to turn off (if you want to align the red to the green without seeing the blue gun and other variations).
2=up, 8=down, 4=left, 6=right, 3=change gun to converge, 5=converge that point.
To exit convergence mode you press 7 once and your screen should look like it's imploding then return to normal and then you press 7 to get back into regular service mode.
I have more info found on the board.

The convergence ICs and the six 1.8 ohm 1watt resistors need to be replaced. You can get the convergence repair kit for your model at www.tvrepairworld.com which has the Two Convergence ICs and the six resistors plus the CD with instructions on how to do the repair.

Your convergence has failed and needs to be repaired. Once quick test is to goto your convergence menu and see if you can adjust red and blue. If not its has failed and needs to be fixed. You can call in a repair shop or you can get the parts and instructions from www.TvRepairKits.com and do the repair yourself. Its a fairly easy DIY fix.
