Here are my own instructions----WHATEVER YOU DO DO NOT ATTEMPT TO ADJUST THE GREEN!

Normal 0 false false false MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;} Toshiba entry to adjust


With the set on press MUTE on the remote.

Then press and HOLD mute for several seconds and while still holding it on the remote press Menu on the front of the set.

A (S) should appear in the upper right corner of the screen. (It means you are in the Service mode)

Press menu again on the front of the set

7 on the remote will call up the convergence grid

3 on the remote will change the color to adjust from red to green to blue(do not adjust GREEN)


You navigate the grid with 2, 4, 6, and 8 buttons.

To stop the cursor from blinking so you can adjust at any point use the 5 button—to move again use the 5 button.


When you finish you exit by hitting 7 on the remote again.


Sometimes you have to try a few times to get into the menu—I have had my problems but once in it is easy.


Let me know if this information was helpful and if you have ANY questions or need advice let me know.

It shouldn't be the convergence chips. You may have blown a pico fuse on the power board.
You should be able to safely remove the convergence IC's and try the tv without them as they only do image correction.

Toshiba TN55X81 Wont turn on but I hear clicking


Pull the three connectors to the yokes on the convergence board. If the set powers up, it's a good chance the STK392-110's need to be replaced. I fixed one today, and it has been running for 6 hours now.

TN55X81 Rear Projection color separation - convergence problem


You shouldn't need to do a board replacement, all you should need to do is manually tune the convergence.

You can do this with the built-in user tool, but there's also a far more powerful set of options in the service mode. To save you the trouble (I advise doing a LOT of reading before attempting any of this) here's a solid set of various tutorials based on what form of "separation" you have occurring:
