The picture squeezes from the bottom up. This results in a distorted picture. Sound and color are fine. Are there any horizontal controls? Is there some way I can adjust the horizontal/vitical for the picture or should I call a repair man?

Re: picture horizontal problems
There is a sevice menu but it is something a repair man has to adjust. Even to get to that menu is a matter of procedure. If the picture is not always squeezed down then adjustment is not the problem. If it is intermitant it could be a bad solder connection on the main board.Sometimes a bad vertical ic and leakey capacitors can be the problem..
Bottom line is there is not much you can do to correct the problem. You are going to need a service man

It sounds like a vertical deflection problem. You mentioned you had a white HORIZONTAL LINE in the middle of the screen. If this line runs from left to right across the screen it's in Verticla deflection. If it runs from top to bottom, it's in Horizontal deflection. I am assuming the problem is a Vertical deflaecion problem. The repairs necessary are most likley to replace the vertical capacitors or the verticla deflection chip.

IT IS LESS WIDTH PROBLEM
It has to be done by tech person as inside tv high voltage is thare so unskilled person should not open tv.
problem is simple.
1 less output from regulated power supply .
2 if width control is there it can be done by that.
Your problem is somewhere between the tuner and video detector circuit.
The signal entering your TV carries: video,red color,and blue color as well as sychronizing pulses for color and horizontal and vertical deflection ( actually vertical sync. is derived from horizontal sync.) along with burst pulses to synchronize the color. After all these, the sound is an fm signal entwined with a pilot signal for stereo audio. WHAT a mess!
After the audio passes through all this, it is detected and sent to the audio processor.
If any frequency has drifted away from it's value then you loose the sound.
SO... your problem could be in any of the tuned circuits or in the audio processor IC (chip). Any component changing value could creat this problem. Most likely the audio processor IC. You'd need to have the set checked out by a tech to find your problem.
Is good that you hit it and it reacts,very likely you have loose conections in different places but for the distorted picture you need to check the horizontal driver transformer and flyback after that is corrected you need to check the complete chassis for loose conections.Take your time.Good luck.
