SOURCE: have 52 inch toshiba regza tv black box appeared
Check to see if the tv is in the text mode of the closed captioning.If not you may need a new main signal board.Also try unplugging the set for a couple of hours to reset it.

SOURCE: Small black box in upper left corner of Sony TV - need to remove
I had a similar problem on my Toshiba Regza but trying my fix couldn't hurt. I use a satellite dish for TV (if you do the same this might work)... I turned off my receiver, took the programming card out, cleaned it with my shirt (especially the part that looks like a computer chip), put it back in the receiver, turned it back on and when everything reinitialized the black rectangle was gone.
Hope this helps.
