Abstract
In a television receiver having a vertical oscillator for providing a source of vertical deflection signals to a vertical deflection circuit, a service switch having normal and service positions is coupled to the vertical oscillator through an interference isolating diode. In the normal position, the diode is reverse biased, allowing the oscillator to function normally while eliminating the introduction of signal interference into the oscillator. While in the service position, the switch causes the diode to become forward biased, thereby disabling the oscillator and collapsing the vertical scan.
