Tv shows the word CAMP in upper right corner with black screen. Can't do anything help

SOURCE: tv guide on our LG tv

If, when selecting the guide, the entire screen is black (except for the preview in the corner), then the digital main board has gone bad and will need replaced.

Hope this helps, please rate my solution.

I would check for dust particles before I attempted any type of repair on the unit.

Dust particles will appear as dark spots that are larger than the size of an individual pixel. It must first be determined if the particle(s) are on the LCD panels or the screen.
