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

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.

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.

Screen is messed up, getting worse

What your describing sounds like two differant problems OR the power supply is causing these two problems .. One would of course be the tuner and the other would be the vertical circuit .. Your going to need to seek out a profesional if you havent a clue about solid state electronicsand A tv is not a place to experiment! Good Luck

Screen split with black bar through center, top of picture shows in bottom

It sounds as you desribe, the vertical output IC and or the b+ feed capacitor off the Hi voltage transformer feeding the vert. IC its required voltage. Not a really hard job to replace, but not for a handi person to do. This should be left to the professional, as there are no user serviceable parts inside this set and with the HI voltage and the safety issues its best to call somesone to assist you with this repair. Good Luck
