Question about Samsung TXG2547 25" TV
The picture on your TV is created by an electron gun firing at the phosphor coating on the screen. The position of the guns beam is controlled by magnetic coils, which are driven by scan circuitry.
Normally, the gun scans left to right, top to bottom to create each single frame of the moving image.
From what you are saying, it sounds like there is a fault in the vertical control system somewhere - basically the gun is going left to right but not up and down, resulting in your picture being squashing down to one row high!
It is unlikely to be a fault with the magnetic coils. My guess would be a faulty resistor that is breaking down (and changing its value) as it gets hot.
It should be a relatively easy to fix, but given the age/value of the TV it might be worth considering a replacement.
