This is the most critical section for a "dead TV" scenario. The standby circuit is always active when the TV is plugged in. It typically uses a PWM controller IC (often a DIP-8 chip like the , LD7535 , or NCP1207 ).

Two Power BJTs (often 13009 series) act as switches. In older designs, one BJT starts slightly earlier to induce voltage on a driver transformer, which then powers the controller. Controller: Most units utilize the This is the most critical section for a "dead TV" scenario
