You need an original working Toshiba remote: two choices here--in the customer menu there will be an option for this and there is a hidden tech menu for finer adjustment all over the screen.

Usually the customer mode works ok--if you find red or blue will not adjust somewhere you have a problem-that aside tell me what you are trying to acheive?

How to fix the convergence on a toshiba TP55D81 tv using the remote control


The convergence is adjusted with the remote by entering a tech menu and adjusting there====if convergence is really bad adjustments are not going to fix it.

The set should have in customer menu a limited convergence adjustment with up to nine points where you can adjust---if it will not adjust there in some way----convergence circuit needs repair.

55 inch mitsubishi rear projection tv red lamp out of adjustment


Have convergence IC's replaced. I believe this unit uses STK-392-570 convergence IC's Only one has gone bad but replace them both, because if one has failed then the other is not far behind, for Blue and Green. One handles Red, One handles BLUE and Grn. There are only two of them in the set, They are the two largest IC's in the entire set.

How do I get into the tech convergance of my


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.

Not able to adjust convergence


Hello there, its possible it is way out of adjustment where you are no longer able to see it.
I don't know if you want to play with this, because t can be very frustrating inching each line into the proper alignment and it maybe better to call a repair person and pay them and also allow them to suffer in that time consuming headache.
I hope this helps.

My colors all of a sudden went out of wack


Is there an advanced convergence setup anywhere in the menu where the screen displays a grid? If so, you might want to get into that and move along the grid to each section that looks off. Adjust until the color falls behind the gridline, and move on to the next. It can be a time-consuming process, but should take care of your convergence issues.

Color convergence out on rc 52 inch projection tv


If it is way out, it is more that an adjustment. It takes a crosshatch generator to do the convergence.

Toshiba TN55V71 55 in. Rear Projection - Damaged


Hi. If the convergence is out but uniformly then chances are its not electrical problem more likely to be physical see if the 3 small crt tubes are loose & can move about. Or was your stuff insured during the move if so put in a claim.
