Black square at center of screen

Hi Tony

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..?

text was turned On I suspect.

Hi big john
To answer your question;
What you have is closed caption(CC) in text mode.
To remove it ;
On the original remote there is a button labeled CC
Hit that button until you see closed caption OFF
Hope this help Cheers

Go into your setup menu and turn off closed captioning. The black square is a box for the text.

look for a button on the remote that says " cc " your closed captioning is turned on, probably in the text mode. turn off the close captioning and your black box will disappear.

check the video with a flashlight against the screen, if present the backlight inverter has failed.

same problem with tv ...cant figure it

I HAVE THE SAME PROBLEM WITH MY SANYO TV THE CABLE GUY TOLD ME HE HAD AN OLDER SANYO TV TO THAT DID THE SAME THING AND HE TOLD ME WHEN THE BOX APPEARS JUST HIT THE VOL + OR - BUTTON AND IT WORKS ALTHOUGH ITS A PAIN IN THE YOU KNOW WHAT WONDER WALMART HAD A BIG SALE ON MY TV.

I seen this problem. On my tv the text caption was on. Check your caption mode, turn off see if problem goes away.

Shut off the closed captioning and your problem will be gone.
