We can set the convergences great but after about 10 to 15 minutes ithe reds lines start moving a little again will not stay in position. It's a widescreen Mitsubishi rear projection tv ws-55857.

The problem - you're setting the convergence settings, but you're not saving them, you're
simply exiting the menu screen. Be sure to save your convergence setting for each
of the three colors. It sounds like you're setting RED last, and not saving its convergence setting,
whereas the GREEN & BLUE are holding their convergence settings, since you're saving them
correctly before proceeding on to RED....

The red and blue convergence wont set correctly how do i set them right i have red bue and green outlines in my picture on the tv

What needs to be done here is to replace the two STK-392-570 CONVERGENCE IC'S that this set uses. I have seen this in hundreds of sets just like yours.

Total parts cost will be under 25 dollars and if you buy local double that or more.

I have available for free, start to finish, step by step instructions for this repair in the set you have.

They tell you everything you will need and how to do the repair.

If this information is of interest to you rate this solution as very helpful as I do this here for free.

Also make a comment here indicating you want the instructions.

Hey I was watching my tv model number ws-55857 and my screen turned an odd blue color yet I would still be able to hear, I turned the unit off and back on and had the same issue after a few more tries it...

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.
This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.
You can get a repair kit with parts and instructions from

Mitsubishi WS-55857 turn on/auto turn off problem

After it shuts off, you need to get a code from the tv by pressing the menu and device buttons together for 5 sec. A code will flash at you made up of 2 digits. Example. 2 flashes a pause and 2 flashes points to a convergence failure. If this is not your code post yours and I will help you.

Cannot adjust horizontal blue convergence on WS 55857

You still have bad grounds on the ICs. Or maybe the solder has fused another pin. If not bad grounds on the ICs you have missed them elsewhere...Really concentrate and look for these bad grounds and check your caps with a cap check. And power resistors too!!!!!
