it could be you have pressed the old teletext service button, look for a button with 3 lines on it in a box and press it or try turning the tv off at the plug then back on again.
You`ve mentioned that ON CERTAIN CHANNELS THE TV WORKS FINE, so your trying to say that not all channels THE BLACK SQUARE APPEARS IN THE MIDDLE O THE SCREEN... my be that black square is generated from the broadcast center. may be your unit is good. let me ask you how many channels that your tv works fine..?
Hi Anthony
Please try to go on the tv lock code features, may be you were able to set time. You just mention that 10 to 15 mints your tv will turn to black and then lock. You need to off the setting.
Hello
Closed Caption function is set to On in your JVC. look if there any button marked as "CC" on its remote control. If it is there, hit it till the closed caption function go off from your tv screen. If there is no such button found, get into its menu option, surf through, and get in to the closed caption option, set the close caption function OFF in that window. OK.
this is pip,,,if you can noy find botton on menu...unplug 5 min....return pkug to wall socket push and hold power botton for 5 seconds....this should fix it!
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
I have a Sharp Tv that had the same problem with a large brownish or black square right in the middle of the screen. It only left about an inch around the edges that you
could see the picture moving in behind the big black block or square.I have DISH sat-elite and the book recomending that I check and see if the "caption settings" were on
or off. They were on. I turned the caption settings off and the large square diappeared.
for anyone who has this problem in the future try the closed caption off instead of lock out codes worked for me.
