Abstract
When a set-top box works, high potential appears at a standby signal end (1D) of an original circuit board (1) to enable a push triode (T1) to be conductive, coils of seven relays are energized, and the common end of the seven relays is connected with a normally open contact end. A television power socket (TVC) is energized, each input/output jack is communicated with each corresponding signal end, and a ground line (10) of the original circuit board (1) is communicated with a ground line (03) of a newly-added circuit board. When the television works normally, seven varistors execute anti-lightning protection on the set-top box and the television. When the set-top box is standby, low potential appears at the standby signal end (1D) of the original circuit board (1) to enable the push triode (T1) to be power-off, the coils of the seven relays are power-off, and the common end of the seven relays is connected with a normally closed contact end. The television power socket (TVC) is power-off, the fire line and the zero line are short-circuited and are connected to the ground, the middle core of each input/output jack is disconnected with the corresponding signal end, is short-circuited with the shell and connected to the ground, the ground line (03) of the newly-added circuit board is connected to the ground, the television then is power-off, and anti-lightning protection is further carried out on the television.
