PROBLEM TO BE SOLVED: To provide a power source controller for combined electronic apparatus which surely suppresses the voltage rise in the operation standby condition of a TV block by a simple circuit constitution. SOLUTION: A cement resistor 20 and a switching element 21 are connected in series to a power line L1 for supplying a voltage V1 from a power supply circuit 15 to a TV block 11 with a grounded emitter terminal of the switching element 21. The switching element 21 is so connected as to input on-off signals from a CPU 10 to a base terminal. When other functional blocks are decided to be in a usual operating state while the TV block is in an operation standby state and the power line L1 is fed with a standby voltage, the CPU 10 outputs an on-signal to the switching element 21 to turn it on and controls to flow a consumption current in the cement resistor 20.
