It sounds that the video output section circuit bard to this TV have some loose solder terminals. Resolder all the suspected solder terminals by applying a little more solder. The video output section board can be located at the neck of the picture tube, will directly plugged on to it. Check it. If you wish to know more details about single color display screens, check this site. It has details to that problem. http://electronicshelponline.blogspot.com/ Pull up previous posts there, either by its

This is not how you explain your problems to others. It should be precise. In this case, you could have said that you connected the cable between the RF out put of set-top box and RF input TV. Or Audio/video output of set-top box to Audio/video input of the TV. Also you did not mention, to which port you had connected the Vedeo recorder and DVD which are working good. Now, it may the volume level of the set-top box at low level which you can try to increase by using the remote control
If you could not sort out the problem explain how you had 'dismantled everything'
Your TV should also have a regular composite video input jack (yellow) in addition to the s-video input. Use that input instead of the s-video. The video won't be quite as clear as with s-video, but you have to work with what the combo gives you.
Sounds like the video output has a problem. Maybe missing the 200 volts from the High voltage transformer.
The vertical circuit may have an issue.
Either way it's hard to diagnose without looking at it.
