    Viewsonic 19" LCD VA1912w problem

    I have Viewsonic 19" LCD VA1912w (I think its similar to ACER AL1916wc) it contain inverter board DAC-12M030.
    When I switch on the monitor the green LED turn on for 3 seconds and than turn off. After 2 seconds it turn on again for 3 second and off again (3 second on 2 seconds off, repeat all the time).
    I replaced all the electrolytic capacitors with new ones.
    But it still not working fine and continue to turn on and off.

    Thanks,

    You probably have failed CCL transistors on the inverter board. Also you might wanna resolder all the pins on the transformer. Additionally there should be a tiny fuse on the board... Pictures would be of great help so some of the senior members can help you out better.

      @aniesns...there is a section dedicated to troubleshooting computer displays.

      You will get more help if you post in there.

        Thanks all.
        I'll try to get new FET's for the inverter.
