When you get the back off, have a look at the Prinz TV121 on radiomuseum which together with the Waltham and Binatone Visionstar are also made in Korea and have a similar look about them to the Samsung.

These televisions are all made for US 525 and European 625 line standards, with their IF response altered, and the horizontal hold (oscillator) control is a user adjustable horizontal oscillator control with a range able to lock the picture on both standards .

Make sure there are no dry or broken soldered connections which could cause the fault before adjusting the horizontal hold control which may have been twiddled with.
