摘要: Method of discharging a picture display tube (3) in device, and device provided with discharge circuit, which the is discharged by switching off generation (20; 23) an anode voltage (Va) controlling (4) defined electron current (3). Prior to generating current, deflection (2) beam displaced beyond visible part screen (32) In this way, without being accompanied bright light phenomena on (32). The decreases safe value there no cold emission phosphor burn-in
