My tv sceen has a stain that makes anything white look yellow.

The color image is comprised of three colors, Red, Green, and Blue.
All the other colors are mixtures of those colors. The yellow picture indicates that your set is lacking sufficient blue drive.

First of all check to make sure that the tint control is not misadjusted.
The next thing is dependent upon the age of your television. If it's an older set that yellow tint is a sign of an aging picture tube.
If it's a newer set, less than 5 years old, have it analyzed by a electronics technician that is familiar with televisions if he is skilled enough he will know right away if it's the picture tube or not.

I have a Symphonic 32" Color TV the picture is red. I need a tv repairman person to come out and look at the TV.

the dives or guns are out of balance. either the blue and green circuits are weak or the red drive is maxed out. when picture tubes are getting old, this normally occurs.
another thought is that the tint is incorrect and saturated. what is the picture quality details?

Zenith Model SY2551S 1996 27" - Green Tint

The core problem with the green tint is the aging of the picture tube, and can be compensated a bit by using either the green drive control usually located on a printed circuit board on the neck of the picture tube or on the main chassis. There will be 3 main controls which will adjust the red and blue as well. If these controls are not present then you will need to get into the service menu and adjust it from there. Don't adjust anything else as you can make the set much worse. Also remember that in order to make these internal adjustments while watching a black and white picture (turn the color all the way down) you will have your hands and arms near live circuits that could shock you and cause injury to yourself as well as break parts inside the set when you pull back after being zapped (voice of experience here) Of course if you can do all this by the service menu then you won't even have to remove the back of the TV.

Blue tint and lines on screen.

Those lines sound like "retrace lines" and several things can cause them. The most common are shorts inside the picture tube and shorted semiconductors in the video driver circuits. They can also be seen if the blue screen voltage is too high or if someone has tampered with the screen voltage control.

Toshiba 32AF41 Power up Problem and Green Screen

My first inclination would be to check the picture tube, especially if the set is over 7 years old. If it is not that, then anything from bad solder connections to capacitors or a defective IC could be the cause. If it's over 10 years old, replace it. No use flogging a dead horse.

Screen has turned a blue tint after turning itself off

I will not bore you with advice which you cannot follow. (90 % probability, looks like the Blue Signal Video Output Transistor has become faulty). This is a very simple "fixable' problem for a Professional Technician. Should not take more than 15-20 minutes.Nothing you can do. Call for Professional help.
