Question about Philips Magnavox 27MS343S 27" TV

1 Answer

Black Box appearing on my screen

Last night the TV was working just fine but this morning the when I turned the TV on it now has a nice big solid black square that takes up about 90% of the screen. It is the same square that you see when pressing the menu button on the remote, except when you click finish the black screen stays there. I do not have the v-chip set to block anything, nor are there any channels blocked. If I perform a scan for the available channels I can see the whole screen but when that is complete the black square comes immediately back into view. This is the same when I change channels, for a very brief moment I can see the whole screen. It is almost like my 17 month old has clicked on some buttons and the DAD cannot figure it out. Thanks for your help- magnavox tv has the same big black box covering most of the screen.  when i use the menu button it goes away for a second... same with any button that i use... like the volume... the box goes away... comes back!  my dad can't seem to get the remote to work now... so i was trying to help him.  this tv is at my parents house.  when i was there i went through the menu but do not remember a cc option.  so could there be another problem?

    I have the same problem on my Philips Magnavox. It's a large black square with numbers across the top and it covers most of the screen. It goes away when I turn the TV off but comes back again often.

Unplug the set for a while , but this problem will return because of a malfunction in the EPROM CHIP , this controls the menu and a few other functions

Black screen with sound


My 47" LCD Smart T.V. was working fine last night. I got up this morning and I have sound but no picture. The VIZIO icon lights up as usual but I get no picture, only sound. From the time I turned it on, nothing appeared on the screen. I have already tried unplugging it for a while and still nothing.

Zenith TV has a big black box in the middle of the screen.


After reading other postings, we figured out that it was the caption box, went to menu and turned it off.
Thanks for the great site, we wouldn't have figured it out without it !

Black box appears in TV screen


The problem with the black box happened to me. I had pushed the subtitle button on my remote by mistake. Interestingly enough, as soon as I pushed the SUBTITLE key again, on the remote, the black boxes disappeared.

It also says CC which means closed captioned-- So the bottom on my remote is Subtitle, and then on the subtitle button is cc...

I hope this helps

Big black box in the middle of the screen


The black box is there because your closed captioning is on and set to text mode. Some channels send the signal even when there is no actual text to display. You can get rid of it by either turning off closed captioning or changing it to CC1 or CC2 mode instead of text. If you can't find those settings, then restore factory settings as directed in your user manual.

Black square


If the picture can be seen on the sides of the black square you need to go to the menu and find the text and turn it off
Usually in the closed caption section
