3.电源开/待机控制在正常收看状态下,IC101(TMPA8809)的輲訛輪脚(P.ON/OFF)输出低电平,使控制管Q006(NPN型管)截止→5V电压经R056加至Q833(NPN型管)b极,并使之导通→Q832b极为低电平→c极为高电平
3. Power On / Standby Control Under normal viewing status, the output of P.ON / OFF of IC101 (TMPA8809) is low and the control tube Q006 (NPN tube) is cut off. → The voltage of 5V is increased by R056 plus To Q833 (NPN tube) b pole, and make it conductive → Q832b is extremely low → c is extremely high
