I have the same samsung 55 inch rear projection TV. Replaced the convergence board two years ago, and it is out again.

This time I will just replace the STK392 IC's. I have read that it is best to upgrade to the higher capacity onces, say the 110, 150 or 180. Question: Is this a direct replacement, or do you also have to replace any resistors to provide them different voltages.
I have seen several different opinions.

Where is the auto convergence button


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.

Note: Changing List and Labels can be time consuming. You can change these at a later time by accessing the

Setup menu.

1. Press the left or right arrow to scroll through the available channels and choose the

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

the last channel available in your channel list. For models D40W20 and D52W20 only, the
Auto Convergence menu appears next.

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
