It sounds to me like one of your color tubes went. If I had to guess I would say the red tube is shot. Its cheaper to buy a new tv almost. You can get a quote over the phone and compare the cost of repair to the cost of the tv.

IS the screen white retrace lines ? Have you looked into the CRT lenses while they are on with a signal applied through the input to see if an image is displayed in the lens lens of the crt? Let me know what the answer is to these two questions and we will go to the next level.

Factory setting will not cure a convergence problem---in customer menu look for convergence and see if it will adjust---if not and looks 3d etc parts have to be replaced and set adjusted.

There are kits for this available on the internet by brand and model number.

May or may not be a do it yourself repair depending on what skills you have.

The picture looks like it is collapsing in (from all sides) and there are three different red, one blue and one green. I have tried to adjust the three picture issue, but nothing seems to...

May be a power supply problem, as the voltage falls the picture suffers. Any power failures in your area? If your line voltage is down it can make for a bad picture.

Blurry tv

there is a focus control in the front of the set behind the front grill there is a door in the middle attached by screws take this off and it should be right behind it. There are six controls on a little box one row says focus and the other says screen don't adjust the screen controls. In some cases these are in the back of the set.

No picture

the porblem of your tv might be somwhere in the video chroma.... the first thing to do is to check for an open capacitor 16V 1000mf path ways to CRT board connection to the main board... if your not inclined with this job contact for a service technician.....gud luck!!

Picture is blurry

it sounds like the focus block or flyback is bad.sometimes you can put nail polish on the adjustments controls to make it stay.usually they are marked from the factory with white marks check and see if they are aligned.but be sure somebody with tech-skills help you.the flyback usually has a screen & focus control.(the big red wire to the tubes or block)
