no way to recover that info without obtaining a good service manual that has the default info loaded. Thats why you should always write evrything down that you change in the service menu and never change anything without having the service manual so you will know what the items sre what your adjusting. I can post a link where you can get a good service manual if you would like.

SOURCE: My convergence on my Toshiba 57'' is out of whack.

did you try to set the convergence adjustment on the remote control? there is a pattern (crosshatch) which you can adjust the convergence of RGB guns,If it cannot be done on earth as it is an heaven... you must open the back cover and look at the liquid coolant at blue gun, that liquid acts as a coolant at the same time as lens, check the level of liquid, usually it leaks and need a repair kit for replacement,make sure not to drop the coolant on the board that's conductor and corrosive.

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
*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
