No picture on LG LCD TV.

Troubleshooting TVs and Video Sources - Badcaps Forums - www.badcaps.net
A friend brought me his 47LG70 TV and complained that the picture went black. I was told the sound was still working when the picture went out. TV powers on, and the back lights come on bright, then after about 5 seconds the back lights dim, but they don't turn off completely.

Pressing the buttons makes a "beep" sound but does not result in anything on the display. The power button "beeps" when pressed but does not turn off the TV, you have to unplug it. No OSD at all.

Bad main board?
