I am going to tell you a simple thing to do to know what your problem may be.
With the set on turn the color all the way to zero. Go to a channel if you can that is in black and white. What color is the screen?
If the answer is that it is blue in the background whoever serviced the set did not and could have removed front speaker grill and inspection plate behind it; there is a black plastic block with three screen controls (red,green,blue) and 3 focus controls (do not touch the focus ones.)
I suspect if the blue screen is there a slight adjustment of the blue screen down will correct this.
The picture with the color at zero should be black and white or gray. If blue is background color it will also be with color.
This is called gray scale; picture with color off has to be gray or black and white.
Before you rate this solution if you have questions make a comment right here and I will advise you.
Check your closed-captioning setting and make sure captioning is turned off (or set for captions if you really want them). You'll find it's set to "text" mode right now. The set is blanking out a portion of the screen to display text it never receives, and you'll only see this when you view a channel where captions are being broadcast. Most sets have a button on the remote for captions, and it's easy to switch modes without knowing it. Then you wind up with the mysterious black box.
