Black rectangular box appears on lower half of tv screen

Our Sanyo TV is approximately 12-15 years old. For the past few weeks we have noticed on three different channels a black rectangular box that appears near the lower half of the screen. Takes up about 1/4 of the screen. When this happens the color dulls on the screen (background, people, objects etc) almost looks close to black and white. When we change the channel and then go back to the 'problem' channel, it looks normal but within a few seconds back to the same problem. This doesn't occur all day. For example we will watch a program mid afternoon, the problem appears for a few hours but later in the evening on the same channels everything looks normal. It seems to be off and on. We thought maybe there was a problem with the tv stations but we checked our other tv and there are no problems with it. Is the TV starting to wear out? Anything we can do to fix it?

    Thanks Cybertech!

    I checked and the closed caption was turned off. Noticed two new problems this morning. On one channel there was a white fuzziness across the screen, moving downward, lasted maybe 5 seconds. Also this afternoon on two channels the screen was flickering which is also new.

    I have a Magnavox MT1901 19" TV. Closed Caption is on. I can get into the menu "screens" but I am NOT seeing an option to turn CC off. Please help.

    I had the same problem on an older Tosiba. I was about ready to give up when I read the post. I tried this and it worked. Thank you to everybody.

    I have the same issue with my Sanyo... the box has migrated to different channels. I have another Sanyo (same vintage) on the same cable system and it has no issues. 99.9 % of the time it is an emply black rectangle that leaves when any remote button is pushed only to return in seconds. One day it began to place a few nonsense text symbols in the upper left hand corner...

Turn off your CC or closed caption

Posted on Apr 01, 2008


I too had a black square appear on my tv which is 10 years old and I figured it was old and just broken, so I got another tv and it had the same square on it as well...I read this and turned off the closed caption which I suspect my 2 year old turned on, and it worked again!

I had the same problem with my Toshiba and this solution worked. Saved me a bunch of money replacing my older TV.

Black rectangular box shows on screen

This is simple: set in the closed caption menu (some cable boxes also have it) called TEXT. Look in the menu and turn it off first in the set and also in the box used if used for signal.

Odd feature and never really took off--designed so some channels like PBS etc could broadcast text.

Black Box on screen

By your description it sounds as though the closed captioning option has been turned on on the TV. Only certain programs are CC capable and that accounts for the box moving from channel to channel as some broadcasts are not CC CAPABLE. Go to the menu on the tv and ensure closed captioning is disabled. This should resolve the issue. If you need more help please let me know.

Black box on screen

you have a closed caption type tv. Search your tv menu (maybe via the remote control) and look for an entry called closed caption, I'm guessing it is set to TEXT. either set it to OFF, or set it to ON if you want to.

Black menu-like box randomly appears, covering the picture

This is a problem with closed-captioning. What you are seeing is a closed captioning box with no captioning in it. Usually this is being accidentally transmitted by the cable company "head end". Just make sure your closed captioning function is completely turned off. if you are seeing it randomly, it may well be coming from your cable company. Is it just on certain channels?

Go into the setup menu and turn off closed captioning. The black box is a text box for CC. Some stations are sending the signal which triggers the box, but are not actually sending any text.

It's the Closed Captioning function I think. I've had the problem with my Sharp TV (and other TV's that have Closed Captioning function). Look at the menu or the manual to see how to turn off Closed Captioning. It might be marked as "CC".
