If the blue is too far out you will need to manually adjust these if you never did this before you could make a real mess, suggest calling a tech.

Toshiba 57H82 convergence problems. TouchFocus


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

Green & Blue Ghosting Convergance problem


Odds are real good that the cooling fluid in the green and blue picture tube assemblies has become contaminated. You can tell by looking down into the lenses with a flash light. Funny thing is the red never gets contaminated because whatever organism is causing the problem can't survive in red light. BTW this may still not solve all of your convergence problems but when the colors are so badly diffused the convergence sensors for flash focus can't lock onto the beam landing.

Blue convergence


SINCE YOU HAVE REPLACED THE CIRCUIT BOARD,THE NEXT STEP WOULD BE CHECKING VOLTAGES GOING TO THE CONV. BOARD COMING FROM THE POWER SUPPLY CIR. BOARD.....IF NO VOLTAGE METER,,SOMETIMES, THERE ARE FUSES ON THE POWER SUPPLY CIRCUIT BOARD THAT SUPPLY THE NEEDED VOLTAGES FOR THE NEW BOARD YOU JUST REPALCED...UNPLUG THE SET,,CHECK FOR A BLOWN FUSE----I THINK THERE IS 2 OF THEM--ONE FOR A NEGATIVE VOLTAGE AND ONE FOR A POSTIVE VOLTAGE FOR THE CONVERGENCE BOARD..GOOD LUCK--SORRY, MIGHT NEED A TECH...TUNICA
