Go into menu settings, closed caption and turn off closed caption... What you're seeing is the text box of closed caption.

Jvc hd 52g787 my position adjustment in my menu will not highlight so i can adjust picture over to the left. help please

Just make the picture status button on the remote control and get the display setting to its factory mode.

The VIDEO STATUS button gives you a choice of three TV picture display settings, including a
display of your own preferences.
Standard - Resets the picture display to the factory settings.
Dynamic - Heightens contrast.
Theater - Gives a rich, film-like look to video. (AV-27D303, AV-27D203 and AV-20D303 only)
Sports - When you watch a sports program. (AV-27330, AV-27320 and AV-27S33 only)
Press the VIDEO STATUS button repetedly to get these choices.

Black rectangle at lower center of screen that blocks most of the tv. adjusting volume takes it away temporarily and then it reappears. don't know if we inadvertently turned on a funcion from the remote.

Take your remote, go into menu, scroll down to captions, right arrow to 1,2,3,off, when cursor is over off press enter on the remote, that should clear the black box and give normal tv viewing.

Black Box in the lower portion of the screen will not disappear

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.

the black rectangle appears as soon as the channel indicator goes off. someone has turned on the closed captioning in the menu of the set. it is in the "text" mode. go into the menu and turn off the closed caption feature.

Adjustable Color Temp. The Adjustable Color Temperature feature lets you adjust the color balance on your TV, depending on the type of light in the room, such as direct sunlight or artificial lighting. On your remote control there should be a button that lets you change the picture mode, IE. Rich, Personnal, Cinema, Sport etc...

Too much yellow in picture

The problem with the set is that the blue gun has gone weak, and not emitting at par with red and green guns in your picture tube. Turn of the blue screen and get the grainy display on the screen (detach the cable) and enter into service mode to fine tune until you get a perfect or black and white grain pattern.

you have to get into the tv to do the adjustment. take the cover off and then look for the CRT tube and follow the yoke cables that will lead you to the printed circuit. you should see some small tiny knobs there. something like vertical phase or horizantl need the verital to adjust the vertical size of the pic..good luck
