Hello, all tension is essential in any electrical device. For its proper functioning.
It's as colleague Willy says, it all depends on the symptom.
In a tv that does not walk you start at the source. Voltage of + b and other source outputs. If these are so good, follow up later. Micro memory voltage. voltage on the horizontal drive transformer. If this is fed directly from the source or not. Directly. Tuner voltages Vertical tension, it is supplied by the source and by the flyback. It depends on the tv. Jungle Tension Chroma tension That also then be supplied from the source or the flyback voltage of scrin. Filament tension
