Question about Toshiba TP50H50 50" Rear Projection Television

TP50H50 Black Box on screen

TV appears to be in permanent DEMO mode but it's not showing any of the DEMO. If I press the DEMO button it's starts, but when I exit the black box still stays on the screen. I got into the service mode and the picture clears, except the little "S" that's on the screen. Any ideas as to how to clear this up?

On my TV certain shows (Craig Furgerson, Oprah, The View)on different networks,a black rectangle, about 1/3 of the picture, appears. I cannot remove it.

That box appears to be from the close caption feautre. If you have the original remote you can disable using the menu and go to audio functions and look for close caption to turn it OFF.
Do you have the user's guide for this TV?
If you do not, could you provide the model number of your TV?

Your description sounds like your unit is in the "DEMO" mode. The procedure to access the demo mode and turn it on or off is in the operaitons manual. If you do not have one you can download one for free at . If you do not care about getting the maual and just want the verbiage to end here is the procedure:

To start the demo mode:

Press and hold the MENU button on the front of the set for 4 seconds.

To stop the demo mode:

Press RECALL, EXIT or Power

Black box in middle of tv screen

This is a background for text, even though you aren't seeing any text at the time. Since it covers most of the screen, it sounds more like a demo mode screen than closed captioning. Go into your setup menu and make sure that neither of those is selected. If necessary, restore the factory settings. I'm assuming that this is coming from the tv itself, and that you don't have a VCR, Tivo, etc. Good luck!

Can't turn off PIP on Sony XBR videoscope TV

Hit the set up button on the TV.
You'll see options to change the language. The last option is to put the TV in "Demo Mode."
Put the TV in Demo mode, when the first screen appears, "Welcome to...." the PIP will disappear.
Hit exit before the screen moves to the "Menu." If you miss it, watch the demo once--it will restart--and hit the exit button the next time you see the "Welcome to" message.

I just did this and it worked for me - i hope it works for you.
