Green screen then blacked out

Sounds like component has failed (diode, cap, IC)
Unfortunately, the days of taking off the back cover of your TV and replacing a defective tube or fuse are long gone. Proper servicing will require troubleshooting procedures that can only be performed by a qualified electronic repair facility or professional television repair person. Ask for an estimate and a realistic appraisal of whether the set can be adequately fixed. Depending on the age and condition of your TV it may not be cost effective to repair.

Black screen but have sound

If it is not a hardware problem, it is most likely the Closed Captioning system.
If you can still see the on-screen menu, go into your TV's menus and disable Closed Captioning.

DELL 42 inch Plasma TV

I have a 42" LG LCD TV and just experienced this today. Watching cable, then the screen went to black, but audio continued. I pressed the guide button on my remote and pic came on with my guide menu. But then went to black again 10sec later and has remained that way for nearly an hour. Tried switching off both cable box and TV, disconnecting and reconnecting cables, but no luck. Finally unplugged mains, waited a minute, then turned back on. Everything seems normal now after the reboot. Phew.
