Where can I read the user manual for a Realistic Model 231x tape head demagnetizer?

The manuals don't have many things to tell. Just move the magnetiser to the head you want to demagnetise. Touch it once and then slowly move the demagnetiser away from the head. If it is far enough (more than 30 centimetre or one foot away, you can switch the demagnetiser of. that is all. Some demagnetisers work on AC, others do have a battery and make the changing magnetic field inside. I could not find the 231X, but to check if it makes a changing magnetic field you could hold it to something made of steel or iron when switching it on. You should feel some vibration. Could be 50 Hz or the ones with batteries have a higher frequency, but could be noticed.
Don't expect wonders from the demagnetiser. With the older tape heads, sound could improve after demagnetising the head, but the later models never kept remnant magnetism.

I am noticing a yellow tinted circle in the middle of my screen. It is noticible when the screen is blank between channels and you can see anything white on the middle of the screen is tinted yellow. Do...

Is it an LCD tv or CRT ?
If CRT try moving the TV to a different location as the magnetic field from another device or even the earth can effect it.
The power switch (full power on) would normally demagnetise the screen.
If its an LCD has any object hit the screen, it could be a child's toy or knocking the screen can bruise the panel.

My generac 40g rv generator will start fine but no power. I noticed that when it starts the microwave will power up for just a second. I can turn the generator off and on a couple of times and then it will...

It may be demagnetised. If you turn off the generator before unplugging the load this may happened. Try to put a strong magnet (like those from loudspeakers) in contact with the body of alternator. I do this in the past and it work.If you do not know how to do this ask an electrician, he can help you .

We have a panasonic ct-36d31e that has developed a degaussing problem now. Rainbow colors - magnets haven't helped neither has power drill placed near the screen. Is there a degauss button on this model...

Hi Tracy,
Unfortunately magnets etc will most likely do all but improve the problem. When a T.V set is turned on it automatically degausses (demagnetises) the tube. However, if the screen does not degauss, its most likely a small electronic component in the degaussing circuit which has burnt out. This component is usually black in color, is rectangular and about the size of of the T.V. screen displayed alongside your question. Its inexpensive to replace(less than $5) and can be found at most electronic component stores.
Please let me know if I can be of any further assistance.
Best wishes,

TV has begun showing patches of a purple hue in the image.

Your picture tube has been magnetised. Now the TV has got an internal degaussing (demagnetising) coil that is supposed to demagnetise the picture tube every time that you switch on your TV. So it is possible that this circuit has failed in which case you need the repairman to look at it.
In most cases however it is caused by the presence of strong magnetic fields near the TV. Look in the vicinity of the TV and remove any strong magnetic fields. these could be loudspeakers, devices with electric motors or simply magnets.
Hope this helps.

Lower right corner has green haze

I am not sure what make and model of TV you have, if it is a standard TV then a ground strap holding you CRT imaging tube in pace might need to be deguassed or demagnetised.

green, red, blue blotches on the screen are indications of a magnetic field corrupting the screens electron flow to the image screen.

Strange colours on television

What do you mean by 'strange colors'? Is it colour patches at the corners and edges of the picture? If that is the case, it is asimple case of Degaussing or Demagnetisation. You need to do nothing, The internal degaussing circuits will sort out the problem over the next 2-3 days. Just make sure you have not placed any equipment with magnets or any magnetic source near your Tv (Speakers, Boob Boxes, Walkie Talkies, etc.
