A lot of Sony sets used a derived power source that came off the flyback transformer. So the horizontal circuitry had to be running so the flyback could supply the other power sources that ran other things in the circuitry. Be very careful with the anode connection in these as it is coaxial. As I stated earlier these were very unique in their design. Not like the typical American made sets of the same time. Very reliable products. CRT’s tended to have a shorter lifespan but that was probably due to a brighter picture/contrast compared to a shadow mask type of CRT.
