Screen goes black when opened fully, reappears when closing it

Check your Closed Captioning settings in the menu. I would bet money you have the "Text" feature enabled. Change it to OFF and you should be all set. I hope this was of some assistance.

turn off you closed captioning either in the menu or with the cc button on your remote.

If it is a lcd screen, the screen is taking a dump on you

The box you're seeing is the "closed caption' box. You need to use the remote and disable CC mode on it, and the box will go away :)

Go to your menu and turn off the closed caption

This is a problem with closed-captioning. What you are seeing is a closed captioning box with no captioning in it. Usually this is being accidentally transmitted by the cable company "head end". Just make sure your closed captioning function is completely turned off. if you are seeing it randomly, it may well be coming from your cable company. Is it just on certain channels?

you have to turn OFF cc - closed caption - in the menu

shut off close captioning. the close captioning is in text1 mode and needs to be CC1 in order to work, or shut it off

go into menu find
cc settings and
change setting to off
(make note of the one thats
causing the problem)

On the reomte control (bottom) left of the sleep button is a cc button, push that until "OFF" appears on the screen. The close caption box should disappear. It worked for me, finally.
