    Tried this, didn't work.
    This appears now to be a computer problem rather than a TV error.

    I say this because if I switch the input from RGB to AV1 the picture appears but is lost again when I switch back to RGB.

    Yeah not quite that easy as I have Vista but anyway did what you suggested and changed screen from 1024 x 768 to 1280 x 768.
    This is not really the best resolution for my screen as the top of the icons, on the top row, in desktop are "chopped".
    Also tried adjusting the refresh rate from 60 to 85 hertz but the picture crashed and I got the "Invalid Format" message. The picture resumed after a few seconds.
    Changed refresh rate back as it was flickering.

    Thanks, let's see what happens.

    Changed resolution to 1152x864 and no picture crash for two days.

    Maybe problem solved.
    Thanks !

Get sound and "invalid format" message displayed instead of picture

Could have still been hit by a surge. Take the back off of the TV and look at the main board were you connect your HDMI. See if it is scorched or components that blackened. Also check your DVD player on another set. Your DVD player could be the problem.

I bought LG 42 plasm Tv last december within 2months it broken because of the earthquake 22feb this year only screen damage can it be fix?

Sorry to read of your misfortune. The display itself is the most costly part of most sets and the price of the display plus the labor cost will come quite close to replacement cost for a new set. If the site below has parts available, they will be less cost than new:

Invalid format

Try rechecking all wire connections for proper placement and fit too and from the tv.
Try adjusting the video format on the DVD, flip through 480p and 1080i. See which format works best with your tv. Do the same with Wii.

See if this helps.

Invalid format when conected to laptop

Go into your control panel. Select display. There will be a picture showing 2 screens. Select the 2nd screen, and lower resolution to it's minimum. Apply and test. Slowly increase till you find what your happiest with. Worked for me using a ASUS laptop and LG60'plasma.
