04 Troubleshooting 1. Common Acknowledge 1.1 Monitor Block Diagram The LCD Monitor contains an interface board, and inverter/power keypad board and flat panel. In Inverter/power/Audio board, power section supplies +14V & +5V for Inverter and Interface board used. The inverter section drives the backlight of panel and the DC-DC conversion.
which composed of 4 build-in diodes, it inverts AC to DC. 1.3.1.2 High Voltage to Low Voltage Control Circuit C804 is used to smooth the wave from rectifier. IC802 is a highly integrated PWM controller. When rectified DC high voltage is applied to the Vcc pin during start-up, the MOSFET Q804 is initially off, and the Vcc pin capacitor is charged. When the Vcc pin voltage reaches approximately 10V, the control circuitry is activated and the soft-start begins.
