Toshiba51hx83 convergence problem

Hello
To access the convergence calibration:

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
adjustments

Yes Saves adjustments.

No Returns to the Advanced Convergence screen allowing

further adjustments.

Note: Before you use the advanced convergence feature, you must
complete the previous steps to align the tubes

Hello
From it menu option, suf through and come to automatic convergence display option and press Ok button on the remote control.

The List & Labels part of the setup lets you edit your channel list and choose or create a

personal six-character label for each channel.

channel you want to edit.

2. Press the down arrow to highlight the In channel list option. Press the left or right arrow

button to add (the box is checked) or remove (the box is unchecked) the channel from the

list.

3. Press the down arrow to highlight the Channel label option. Press the left or right arrow

button to scroll through the available list of 25 most common labels. The last option in

the list allows you to create your own six-character label for the channel (the first letter of

the label is highlighted).

4. Press the 1 or 2 number button to change the first letter of the label.

5. Press the right arrow to highlight the second letter, then press the 1 or 2 number button

to change the second letter, etc...

6. When you are finished creating your label, press OK. For model D34W20, your TV tunes to

Auto Convergence (for models D40W20 and D52W20 only)

Your TV's picture tubes might have been disturbed during delivery or after you moved the TV,

causing the color in your TV to be out of alignment. The colors adjust by starting auto

convergence.

1. Press OK to begin auto convergence.

2. When the auto convergence is complete, the Red center convergence menu appears. The

cross in the middle of the screen should be yellow. If it is not, use the arrow buttons to

move the red cross to overlap the green cross. Press OK when adjustments are complete.

3. The Blue center convergence menu appears with a cyan cross in the middle of the screen. If

it is not, use the arrow buttons to move the blue cross to overlap the green cross. Press OK
(the TV tunes to the last available channel in the channel list).
Ok

Adjust the convergence or reset it to factory default. Use only the remote when adjusting convergence. The front controls have no effect.

1. Press action button to enter MENU.
2. Navigate to SETUP.
3. Scroll down to CONVERGE.
4. Press VOL > to select.
5. Press CH buttons to navigate up or down.

   center of cabinet.
10. Press ACTION button to display red center correction screen.
11. Use the navigation buttons on the remote control to align the red cross with the white cross pattern at the center of the screen. To prevent picture tube damage do not leave test pattern on for an extended period of time.
12. Press “0” on the remote control keypad to display the BLUE center correction screen, repeat procedure for adjusting blue. If needed press “0” again to return to RED correction screen. An adjusted cross pattern appears white with a minimum of color protrusion.

Remote Control must be in TV mode.

1. Press ACTION button to display red correction screen.
2. Press the 1 through 9 keypad buttons on the remote control to select the desired convergence position.
3. Use the navigation buttons to align the RED cross with the white cross pattern.
4. Press “0” on the remote control keypad to display the BLUE correction screen, then repeat procedure.
5. To exit press ACTION button repeatedly, then press CH up.

3. The Blue center convergence menu appears with a cyan cross in the middle of the screen. If it is not, use the arrow buttons to move the blue cross to overlap the green cross. Press OK.
   

The convergence output IC's need to be changed. A very common problem with all projection tvs.

The convergence IC's need to be replaced. STK392-110. There are two chips and they both should be replaced in tandem. After that a simple customer convergence is all it takes to get it back to normal.

Search around there's better descriptions about the solution to this problem at fixya than what I just typed. But basically you replace those two IC's and then check all the resisters and you're good to go.

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.
Here is an example photo....

Sounds like convergence issue--replace Stk IC's mounted

on large heat sinks. Check power supply for open fuse device.

Re-check convergence alignment.

If you did not use heat sink compound then you probably have not hurt the new IC's yet but you should remove them and add the heat sink compound NOW. If the convergence IC's are bad then you will have access to the convergence menu but the adjustments will have no effect. The fact that you switched the IC's and got the same results shows that the IC's are good. If your red convergence is still way out when the new IC's are installed then the old IC probably burned out the low value resistor associated with the Red Vertical (RV) channel.

you have bad convergence ics
