I was using the remote control that came with my cable box to control the television, trying to trigger the sleep mode, and something that I hit seems to have put the television in some alternate display mode. The color set up has changed, getting darker, but that I can still change with the normal menu setup. The problem that I have is there are black bars at the top and bottom of the picture. I see no way to get rid of that. Using the same sequence of buttons on the cable box remote only produces the same effect, i.e., if I change the color settings, they go back to this default setting. I appreciate any help on this. (I am not sure if this would help, but the cable box is a Motorola, the remote is model UR4-DCT, and the sequence that triggers this even is [TV], [Menu], [Left Button])
It sounds as if you have accidentally entered widescreen mode. Explore the on screen menu to find the widescreen option & switch it back.

Ok, the other possibility that you can try is the vertical size control. This will be found in the on screen menus, or possibly a control on the back of the set.
If this fails, then the set has developed a problem in the vertical deflection circuitry & will require the attention of a qualified TV technician.

If you are watching television and you see black lines on the left and right sides of the screen, check to see if you are watching an HD broadcast or a standard definition broadcast. You can do this by bringing up the TV guide menu on your remote. If the show is in HD, it should take up the full screen. However, if it is not HD, bars will be present on the left and right of the screen. That is because standard definition programing is in 4x3, which will not take up the entire screen. If the picture you are watching not only has black bars on the sides, but on the tops and bottoms of the screen as well, your "Zoom" mode has somehow gotten off-kilter. Press the "Zoom" button on the remote until the image appears correct. If this does not work, power down the television, wait a few moments, and power the TV back on. The image should be correct now. If the image on the screen looks stretched or squished, this is because your HD cable receiver is not set up properly for your widescreen television. Press the "Menu" button on the receiver

There is no mention of a widescreen mode in the on screen menu.
