Question about Hitachi 50UX57B 50" Rear Projection Television

1 Answer

Can't get rid of black box

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.

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.

This caused by the captions, get the remote, press menu, scroll down to captions, right arrow press 1, 2, 3, off when the cursor is over the off press enter on the remote and that should get rid of the black box.

There is a large black rectangle in the middle of the screen. It goes away for a second when I press the EXIT button on the remote and for about 4 seconds when I press the RECALL button on the remote. ...


This is a text box. This can be turned off under the closed captioning. There should be a cc button on your remote or the closed captioning features can be accessed from your television's menu. Turn closed captioning completely off to get rid of these text boxes.

Keep in mind that closed captioning can also come from your cable box or satellite receiver as well.

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!

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.

Large Black rectangle on bottom half of screen


My mother-in-law had this problem on a Quasar for two years before she finally mentioned it. The rectangle is a text box for closed captioning or for a demonstation list of features, but without the text. I restored the factory presets and poof... problem solved.

Look in the manual and find how to restore the factory settings - it will probably be some weird combination of buttons that you would never guess. On her set, which has a built-in VCR, it was simultaneously pressing "play" and "FF" (on the set, not the remote) for five seconds until the set powered down. Yours will probably be something different but equally odd. That should get rid of the black rectangle. Then you go through the initial setup and you're back in business.

Large Black Box Showing up in middle of screen.


When a black box appears on the screen it means that your closed captions are on and set to TEXT. When the closed captions are set to CC1, it puts the words on the screen and when set to TEXT it puts a black box in the center of the screen. Go into the set's menu, navigate to the closed captions page and set the captions to OFF.
