Question about Zenith C27A24T 27" TV

1 Answer

Large Black Box Showing up in middle of screen.

Out of the blue a large black box shows up in the middle of the screen. It is a perfect rectangle and takes up about 80% of the screen. When you move the volume button or change a channel it goes away but comes right back. Used to be able to get to HD channels and it would not happen, now it happens on all channels regardless of the input, DVD, Cable box, direct cable. A large black box appears out of the blue and takes up almost all of the bottom half of the screen, then letters appear on it. but when i turn the tv off then back on it goes away.

My 32 lcd tv a black rectangle apears on aprox,

If it is a large black rectangle that blots out the middle of the screen then you need to check your CC (closed caption) setting. Make sure the closed caption is turned off. I'm not up to date on the newer sets, but a lot of the older ones had more than one CC setting. One setting ran the captioning across the bottom, another put it in a big black box in the center of the screen. Most places didn't support the full text so all that showed was a big black rectangle on the screen. Since I'm not sure exactly what your rectangle looks like, this is my best estimate of your problem. Hope this helps.

Black box in middle of tv screen

This is a background for text, even though you aren't seeing any text at the time. Since it covers most of the screen, it sounds more like a demo mode screen than closed captioning. Go into your setup menu and make sure that neither of those is selected. If necessary, restore the factory settings. I'm assuming that this is coming from the tv itself, and that you don't have a VCR, Tivo, etc. Good luck!

Large dot in the middle of the projected display

there is a burned-in spot on the polerizer light filter for the blue lcd. it makes sure the light is blue coming through, that's why it is black on a blue screen, and yellow when the red and green are the only light showing through. it needs to be replaced. pat # PFiLW0213CEZZ.

Can't get rid of black box

You have your TV in the "Teletext" mode. Go into the TV menu and select the closed-captioning menu and turn off the text function. What you are seeing is the result of the TV's captioning circuit latching onto a false text pilot signal and then throwing up the black box on the screen.

Black box in middle of screen

Note that the large black box goes away when pushing buttons on the tv (ex: the black box will disappear to show the volume setting when changing the volume on the tv but it will cover the picture and the menu display of the dtv box).

This is caused by the closed caption setting of the television set NOT the captioning of the converter box. To fix this you must open your television's menu, find the ccd/closed caption option, and turn it off. This is a frustrating problem as when most people are told to shut off the captioning they try to do so at the box.

Normal dtv box captioning will appear as a small text box at the bottom of the screen as you would expect - not as a giant black rectangle that covers most of the screen. If you do want to shut this off too you will find that you can't do it through the usual menu options (the menu will only allow changes to font, color etc.) - there should be a ccd button on the remote that when pushed will scroll through ccd-1, ccd-2,... off.
