    Acer Monitor Power Supply 79069140..R Backlight Problem

    Hi
    I am actually repairing a Acer monitor power supply 79069140..R. When i opened it , there was a lizard just under the Main Capacitor 100 mf 450 V. I replaced it with same value. When i tested it, the power led turns green for 1 sec, then orange for 1 sec and then off for 1 sec and the cycles continued like that. When i removed the 4 connectors going to the screen from the inverter section, the power led turns green for sometimes and then orange (stand by mode), which means that the monitor power supply is functioning as it should be. But as soon as the 4 connectors are connected to the inverter board, the power led blink in the order as stated above.

    I don`t know what is wrong with the inverter section, there no bulging caps. Can someone help me please, i am attaching pics of the front and back of the board.
