To enter the service menu.

1. Changing the input to an unused input (i.e. Ant B). Turn off the set and wait for the fan to turn off. 

2. Hold input and power buttons on set down simultaneously. When service menu appears, release both buttons (input button first). 

Note any settings before you change them. I haven't challenged it but I have read online in the forums that entering the service menu may void your warranty. Service manuals are available online at ebay.

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.

I'm having a problem with my Toshiba 57H81 Rear Projection TV where there is to much green in the picture. Adjusting the tint and colors only helps some. I notice when I turn the TV off rather than a ...


Two things---first if you don't mind give me a vote here--I am rated on how many problems I fix

Second---with the original remote go into the customer menu and select Convergence---see if you can adjust the other problem that way---I can if that helps you email you the instructions for going to the tech menu to adjust convergence all over the screen and and saving those adjustments----if you find the convergence will NOT adjust in some area of the screen you may have a convergence problem.

I would appreciate a vote here for my help and if you need the directions for the advanced convergence let me have your email.

The kit comes with original Sanyo STK IC’S , not those cheap aftermarket or china made IC’S full pictorial directions, the thermal paste, resistors, the correct Pico fuses, AND free live on-Line tech assistance in case you run into a problem with the repair. They ship out 2 to 3 day Priority mail, the next day in most cases GOOD LUCK!!!

Hi,

Hitachi Convergence

Check out the Convergence Gallery. If you see the colored outlines or color shading as in the Gallery, you have a convergence problem.

The repair for a Hitachi requires the replacement of the defective IC or ICs and any damaged or smoked resistors. Some models don't have a separate convergence board and the board is not usually available for the ones that do have a separate convergence board. Usually there is little alignment required after the repair. If you play with all the adjustments before the fix, hours may be spent re-aligning.

If you change the original ICs with substitute "new and improved" parts that are talked about in the blogs, you will probably create problems. Use the original ICs and resistors.

Don't monkey with it.

This is a delicate and difficult repair. If not done by someone with some electronic repair experience, the TV will likely end up as junk or cost considerably more for a tech to fix the damage done.

If you live in Calgary, call me. If elsewhere, find a competent tech.

Picture warping


Yes this is a typical convergence problem, and there are two convergence Amp Ic's that are in need of replacing. If you have any solid state repair experience, you may be able to replace these IC's yourself, but if you do not have any solid state printed circuit board experience, play it safe and call in a tech to assist you in this repair.
