Question about Toshiba 46HM95 46" HDTV

1 Answer

Black Box My Tv screen all of a sudden posted a black box across the lower middle of the screen. From the manual, I assumed this is a captioning issue and attempted to follow the steps to turn off captioning (of course I never turned it on, but whatever). This is not a cable issue, because the same problem occurs whether the input is set to the DVD, or to other inputs (Xbox). When I hit the menu button, the menu options appear, but I have no control over the cursor or the selector. All it allows me to do is to select the presently lit feature (picture quality and settings) and modify that. When the menu is closed, the image of the tv is whole for about a second, then the black box appears again. Perhaps on a related issue, for a few months now I have noticed that the captioning will turn on, and gibberish will begin to appear at the bottom of the screen. I've been able to easily get rid of that just by turning on the menu and off again with minimal annoyance. My guess is that the problem is with the operating system, or whatever controls the functions of the television, but I have no knowledge of televisions, so I am just guessing. Any help would be appreciated. Thanks.

Hi Krautner, We have a Toshiba and experienced the same problem this morning. It is very similar to your symptoms: big black box in centre-lower part of screen. It sometimes disappears momentarily when you select a feature such a "mute" for the same amount of time the screen displays that function. Once the "mute" signal disappears, the black box comes on again. I fixed the problem by turning off the close captioning function. Somehow, it had actually got switched on. It runs fine now. I suppose you have already found a fix since you posted back in May....but hopefully this helps you or someone else putting in a similar search for this fix. Cheers Geo

A disturbing black rectangle is in the middle of my screeen>


This question was posted under "barcode scanners" but I'm going to assume you actually have a TV set problem. Check your TV's closed-caption settings. You probably have turned captions on and set them to "text" mode, and the screen is being blanked out where the text should go. It's easy to do this with most remotes, where there's a single button for caption settings. You can hit the button and change modes without knowing it. Once you turn captions off the box will go away.

Black box in middle of screen


It's a text box for either closed captioning or demonstration mode. Go into the setup menu and turn off closed captioning. If you have trouble doing that, then just restore factory settings.

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.
