Question about Vizio L30WGU 30 in. HD-Ready LCD Television

1 Answer

LCD Screen Flashes briefly with good pic, sound is OK...picture is on for only a sec.

If I unplug both CN1 and CN3 and plug one or the other in while power is on, I get a brief good picture. These connectors are on the power board and go to the inverter board. Suspect a cap or something...Any ideas?

Thank you kindly in advance for any ideas.

    My screen flashes briefly also.
    Where is best place to purchase inverter board?Iheard they are easy to replace. Is that true?

It is most likely one of the transformers on the inverter board. They are rectangular in shape and there are 8 of them. Replacing the inverter board usually fixes the TV. db

Vizio sv422xvt lcd tv , freezes shuts off and reboots at random, need fix advice, total reset didn't work

Sounds like you might need to replace the main board on the unit. Make certain you get the right one or it will not work. E-Bay might have one.
