55 INCH TOSHIBA, CONVERGENCE WON'T STAY SET, WON'T ALIGN

The edges of the "boxes" around "info" are not straight. I can adjust each individual convergence location(0-9) but they seem to change again later. Also, the text on the screen, especially near the edges, shows the misaligned convergence. Have electronics experience, was hoping I could just swap our convergence ICs. 55H70 model.

    Here is a quick test....

    Using your original remote go-to the settings menu then goto the convergence section.

    Try to adjust the red and then the blue convergence.

    You should be able to move RED and BLUE in all directions - up, down, left, and right.

How do i adjust convergence on a 55 inch toshiba


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?

The picture is bowed and has a rainbow affect around the edges


Projection sets have two very common problems.

The first common problem is convergence

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped or bowed
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

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.

Toshiba theaterview 50in rear projection tv


Look at it on the QVC channel where you have boxes with straight lines. If any of the 3 colors are bowed and 1 inch off, then it needs parts inside. If the colors are straight and only 1/4 inch off, you can adjust it. Using the remote, in the menus find convergence to adjust. Your user manual will explain it. At WWW.Toshiba.com you can download the manual if you do not have it.

Center screen convergence problem


The convergence adjustment on the TV set are for the center adjustments ONLY. if you cannot get them in or they are way out, then you have a convergence IC problem. Dont feel bad though as it happens to every rear projection set ever made. Good Luck
