Black rectangle at bottom of screen when playing dvds on sony dvd player

your dvd player needs its own connection as does netflix and cable,get a new hdmi cable for each

on the a/c adapter, (red yellow and white.. unplug your yellow connector and if that doesn't fix it, then plug it back in and unplug the white one.

Yes! you are right, this almost sounds like a captions problem, check the DVD/VCR Combo menu, if it has captions turn it off using your remote.

it sounds like someone turned on the text box on the closed caption feature on the set there may be a button on the remote or look in the set-up features in the main menu
Techman.

check the closed caption option in the menu, should be set to off or cc1
thanks

I signed up for the "chat" and the problem was solved very quickly. Thank you - great service!

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.

This sound like a problem with the Closed Caption, on many sets if the C.C. is set to text a black box apears, and since it only happens on DVD you might look at the DVD menu and see if it has this Text featcher in the Closed Caption menu and turn it off

try pal-ntsc anyway

Go to your TV remote, in the menu find the closed caption or sometimes it is on the remote itself. Turn off the closed caption. this should solve your problem. Good Luck
