closes the SW on the T2 board.
It is monitored by DE-micro (pin63 of IC5) and turned off the lamp when it is
opened.
Fan rotation is detected by ''FAN-PROT" and the DE-micro (pin92 of IC5) turns
off the lamp when it is ''high".
When the ''LAMP-PROT" (pin83 of IC5) is high, the lamp is not turned on.
If the ''LAMP-HV-DET" (pin94 of IC5) is low at the same time, it classified as
no high voltage of the lamp driver.
When no ''D5V (SW_5V)" is detected, pin 129 of TV-micro (IC7002) is low and
it turns off the main power. (for example, blowout of thermal fuse).
When DC voltage is detected at the speaker output, ''SP-PROT" (pin102 of IC5)
is low and it turns off the main power.
