Zenith TV picture shrinks

I got a used Zenith 25" tv (model no. SMS2549S) recently and it was working fine for about a week then one day when I changed the channel the picture shrunk to the top 2/3 of the screen with the bottom part (and also a little of the top) went blank (dark). I could see the channel being display but the image was getting squished kind of, sorry don't know the right jargon for that, hope you know what I mean. I tapped the tv on the side a few time and it worked one time (full picture was back), but few minutes later the problem came back. With trial and error I found out that if flipped it upside down and tapped it lightly in one area the picture goes back to normal, but just for a few minutes and the problem re-appears. TIA

Is this something simple that a complete novice can do, I'm not even sure how to open up the console? I Can't seem to even find a repair manual for it online.
