Problem with picture

I have daewoo model CTS 2090. The color picture is great except there is
a black rectangle (approx 12'' x 5') covering part of the lower half of the picture. This happens even when I am watching a DVD, so I figure it's the TV.

There is a black rectangle that covers the bottom of our screen and it will pop off for a second when you change the input but then comes right back on

Turn off closed-captioning. You have it turned on and set to "text" mode, and the set is blanking out the area where the text would go if there was any.

Tv screen is black except for 1 horizontal line of color

The line is there because the vertical deflection unit - the one that spreads that line across the entire screen to form the image - has failed. Replacing it is a job for a professional, or at least an experienced amateur, and the parts will be quite difficult to find for such an old tv .

Sounds like your closed caption may be on and here is how to turn it off..

1. Press the menu button until you get to the "SPECIAL" menu.
2. Make sure that Closed Caption and CC on mute are both set to OFF.

This should make that black box go away...

Good Luck and please rate this solution...

A black rectangle is displayed on the screen

the black rectangle appears as soon as the channel indicator goes off. someone has turned on the closed captioning in the menu of the set. it is in the "text" mode. go into the menu and turn off the closed caption feature.

Color adjustment on Sony 36" Trinitron

Unfortunately, the CRT (Picture Tube) is reaching its very end. Your set is not feasible to service even if the CRT would still be available from Sony or any jobbers.

I would be seriously shopping for a new TV set!

Black rectangle appears on every channel


somehow your closed captioner has been turned on and within that the text option has been turned on. If theres a menu button on the front of the tv you can navigate with the menu button and either the volume or channel buttons to select options and then navigate to closed caption and turn it off. If you dont have a menu button you will have to get a MID priced universal remote which will have your menu button programmed within it, some newer directv remotes have the menu function, you can go to radio shack and tell the guy there your problem and he will will most likely set you up with the proper universal remote which will enable you to shut that off.

good luck!

there is a broken conductor strip or broken solder joint on the circuit board near the power input jack. do this: 1.) disconnect tv and open panel to expose circuit board. 2.) using a flashlight and magnifying glass, look carefully for this broken solder strip or solder joint. Flex board slightly if necessary to aid in finding the break. 3.) repair it using solder iron and flux solder and scratch copper conductor slightly to aid in "wetting" the solder fix.
