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.

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.

See my solution <http://www.fixya.com/support/t2795690-convergence_off_blue_line_only_vertical>.
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. -Ken

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.

Tips for a great answer:
Press the MENU button on the remote.
2. Press 3 to select the Screen option.
3. Press 4 to select the Adjust Projection TV option.
4. Press 4 to select the Advanced Convergence option (the
Advanced Convergence screen appears).
The green pattern is fixed. The red and blue patterns are adjusted to
the green pattern. The Red Convergence appears first by default.
5. Colored cross-hairs show the current adjustment position on the
grid. To move the cross-hairs to a different position, use the
CH+/- buttons on the remote to move the cross-hair highlight up
and down, and the VOL+/- buttons to move it right and left.
6. Use the arrow buttons to adjust the red pattern. Each press of
the arrow button makes a slight adjustment from the center of
the cross-hairs - you can press and hold the desired arrow
button to make a faster adjustment, and then make fine
adjustments with single presses of the arrow button.
7. Press the INFO button to switch to Blue convergence and follow
the steps above to adjust the blue pattern.
8. Press OK to exit. You will be asked if you want to save the
Yes Saves adjustments.
No Returns to the Advanced Convergence screen allowing
Clear Exits screen without making any changes
Note: Before you use the advanced convergence feature, you must
complete the previous steps to align the tubes

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.
