2.3 Overvoltage Protection
With the voltage divider R6038, R6039 and R6040 the +B voltage is
controlled. In case of failure, the zener diode D6009 is switched and a
"high" signal is sent via resistor R6042 to pin 13 "OVP" at connector
CN6006. Please refer to Figure 2.5
2.4 Overcurrent Protection
R6021 is the resistor to control the current on the +B line. If the voltage
via R6021 goes to high the transistor Q6010 is switched. Then
transistor Q6005 is switched and the error message "OCP" is at
CN6006; Pin 12. Please refer to Figure 2.6
2.5 Protection Circuit of Power Block
• In case of OVP or OCP, the information goes to the A board via
CN6006 and then direct via CN0001 to the micro controller on the M
board pin 24 and pin 29.
• The main controller on the M board switch the main relay RY6001 on
the G board and the TV set switch into standby.
• In case of OVP the LED flash three time.
• In case of OCP the LED flash two time to show the error to the
outside.
