Hi, I would buy your TV

SOURCE: Black box appears in middle of screen

go into the menu and look at the closed caption option----if TEXT is highlighted--this is your problem---select CC! or if it has it OFF.The TEXT will only appear on certain channels and it most likely was activated by someone changing the closed caption options. If this has been helpful give me a vote to let me know.

Most a likely a problem with your Y-Sustain board which will then not drive the screen giving a black picture. The fuse on the board may be open circuit & need replaced but most likely you will need to have the sustain board replaced.

**This is NOT a solution**

I was wondering if you were able to fix this on your own. I am have the exact same issue with a 42LG30

SOURCE: Lg 42lc7d turns on to blank screen doesnt respond to any request
