A black rectangular black screen shows up but..... sony trinitron


Check the set up. You may have closed captioning turned on which will show up as a black box if there is no closed captioning information for the selected channel. If that fails to resolve the problem, update this.

Thanks,
Dan

At random a black retangular box appears on the screen


Go into the TV's closed-caption settings and turn off captioning. You'll find it's set for "text" mode right now. What's happening is that in text mode, the set blanks out the part of the screen where the text will go but there isn't any. On channels or programs where captions aren't being broadcast you don't see anything. With the captions turned off the box will go away.

Blackout area on screen


Make sure the TEXT and CAPTION options are turned off.

I am not sure about the Sonny's, but on my Toshiba a black box appears when I inadvertently leave one of the close captioning (CC) on for text or captions on (such as CC1, CC2, etc.).

Did the black box disappear or disappear and then re-appear?
If yes> TV station is broadcasting a caption text signal without any textual data. > Press the RESET key twice.(Customized settings will be reset to factory defaults).
To retain customized settings just turn captioning OFF.

1. Press the CAPTION key on the remote control.
2. Use the 0 key to select OFF, cap1,cap2,Text1,Text2,or Quickcap.
