4 Scrolling black boxes with the picture showing in the background

well 1st before id go changing any parts I look at weather or not the input is selected correctly over to the input that im providing a known good picture signal with (antenna,cablebox,etc.), you'd be surprised how many times I get a call and I go and use the input select buttons on set itself (NOT REMOTE) and whhoolaaaa! there it is , of course I always hear next I didn't change that !!
a short comings of todays modern TV's if you arnt having any signal into it ,the screen is black and the set-up menu wont display on a black screen

try running the auto tune program in the set as what you describe may be out of tune for the stations

The black box is likely in the CC area labeled TEXT and can come from the set or a box connected for signal.

The other issue sounds like PIP or picture in picture is engaged.

Both issues may require the original remote to turn them off.

Set would seem to be either in PIP (picture in picture multiple mode) or the black box might be the TEXT feature which is found in the closed caption menu.
