TC-L37DT30 Standby Power (1)
When the TV is plugged in, AC voltage is applied to the standby circuit of the power supply circuit to produce
STB5.8V. The STB5.8V is provided to the A board via pin 15 of connector A02. The STB5.8V is regulated to
STB5V and applied to the application specific integrated circuit (ASIC), IC5000, for conversion to STB3.3V.
The STB3.3V energizes IC8001 to prepare the internal microprocessor for program execution.
The 3.3V from the voltage regulator is also applied to the remote control receiver and power LED on the K
board through Pin 3 of connector A10/KA10.
If the STB5.8V is missing, the TV is dead (No power)
