1.Are these lines only in the upper 1/3 rd portion of the screen?And is there a clear demarcation between this area and the lower portionb, where the image is perfect? 2.Or is thin Horizontal lines evenly spaced around an centimetre apart? If it is the first case, then there si a problem with your TVs SMPS. It is not generating the required regulated 110V required for the TVs functioning. If it is case 2, then there is a simple adjustment at the back - 'SCREEN'. This adjusts the Screen Grid Voltage, and by slightly lowering it, this problem will go away.

Look for bad capacitors in the vertical deflection amp, and in the pin amp sections. This is common on most of these types of TV sets.
The caps tend to go high in ESR with age. It is best to use an ESR meter to find the bad caps. It will be a lot faster than workign out waveforms with a scope.
