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 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.

Have Sanyo DP50740 Plasma tv and Dish Network receiver. This morning I turned TV on and receiver on and Black screen appeared on TV with floating no signal box with white letters. I do not have the tv


Wait a day or so. They could be working or configuring the Satellite. If you had no trouble whatsoever in the past weeks, why would it suddenly let you down? Obviously they may be doing something that made the Satellite transmission inoperative for a few days. if the problem persists, then there are the proper people to seek. You can also seek advice from other Satellite dish users. if they have same problem, then it's obviously technicians are working on the problem.

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 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?

Sony Trinitron KV-32S40 32" TV problem


This is a simple and common problem. The solder joints on the vertical output IC have cracked loose. I actually did a housecall on the exact same set with the exact same symptoms this morning! A good tech will resolder the pins of the vertical output IC and all other major solder joints on the main board and the set will play fine.
