A black rectangle showing in the middle of the screen this appeared suddenly


this sounds like screen burn with rear projection and plasma when a picture is left sitting still on the screen sometimes it will burn in to the screen rendering it useless i left my ps3 paused on my old tv then when i changed to bbc one it still had a faint call of duty pause screen in the back it can vary from things like that to logos to your black rectangle the only way of repair is by replacing the screen all toghether i would advise you to just take the screen off and start using the tv as a projector if you cant find a screen it is only a bit of ribbed plastic but very hard part to find

Yellow Screen over most of the TV?


This is a common problem. Your convergence has gone out.

Common symptoms are...

1) 3D Video
2) Warped Video
3) Convergence menu does not adjust the red or blue correctly.

Black rectangle on the screen


That sounds like the Closed Caption function is turned on. Go to the menu and turn it off if it is on.

I have little boxes at the bottom of my screen. They appear when there is a light picture on the screen. Three rows of small rectangles. Help! Mitsi 65 that just got the blinking green light fixed.


you're probably used to watch tv with le closed captioned on. On big sceen tvs, the closed captioned text will burn the 3 crts (green, red and blue) it is written on the first page of your owner manual and there is nothing to do to fix it. it would very costly. sorry

Black box in middle of tv screen


This is a background for text, even though you aren't seeing any text at the time. Since it covers most of the screen, it sounds more like a demo mode screen than closed captioning. Go into your setup menu and make sure that neither of those is selected. If necessary, restore the factory settings. I'm assuming that this is coming from the tv itself, and that you don't have a VCR, Tivo, etc. Good luck!

Sony kp-65wv700


take the back off there should be a small rectangle with 6 buttons on it 3 for focus and 3 for the G2 (screens) some models have this control in the front behind the speaker grille behind an access panel and others have the control switch on the circuit board that is attav=ched to the crt neck. Either way its just a small switch much like a volume switch but smaller. Depending on what chassis you have it will be in one of the 3 areas I have mentioned. just turn it down a little. If that doesnt take the lines away you will need to trouble shoot the blue drive circuit.
