The fault is with its video output stage circuit card. This card can be located at the back of the CRT itself, will be plugged directly to its back. Check all the solder terminals to this board, for any loose solder points. Re-solder all the suspected solder terminals, by applying a little more solder to each of it. The fault is technically called 'one color predominant screen'. If you wish to get some details; check the site linked here.Viewing it in "Mosaic" will make surf easy.

SOURCE: TV screen on video 2 and remote died

The only way your going to change the video mode is with the original remote. If you need another remote go to http://remotes.com or call 1800 remotes Theres a button on the upper left hand side of the remote called video mode. A universal most of the time will not work this function. You could ask around to your friends and buddies or relitives if anyone has a working Sanyo remote or go to a local retailer that sells Sanyo and see if he would let you borrow one for a little while so you can switch out of the video mode. Good Luck

SOURCE: 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

SOURCE: black square in the middle of screen

your closed caption is on, this might be set on the cable box or the tv, look in the audio or set menu. If you dont have the remotr you should be able to navigate the menu on the tv with the onset controls

Testimonial: "wow its been over a year but what john said was exactly the problem. 20 seconds of figuring out where the closed caption settings were in the menu and problem solved."

Was watching tv( Toshiba Regza)and the screen went blank.


I have the same television and ocasionally the sound shuts-off, but I still have a picture.
What type of cable system do you have? What kind of converter box? I am trying to find out if it is the TV or converter box. I change the channel a couple of times and the sound usually comes back.

Daewoo DVN-14F6N


Same problem...Went to Goodwill Store, they usually have a large basket of remotes. I found a Daewoo remote for a TV only, HOWEVER on the bottom it has a AIR/CABLE button. The remote doesn't say Daewoo on it only..."Remote Controller R-25B03". The rest of the button of course work with the TV portion of the DVN-14F6N.

Take time to get used to the settings, you may think the screen looks dull at first. The truth is most people have way too much contrast on their TVs.
These settings will also work for Cable or Dish hookups, in which case you may change the Noise Reduction option to Medium to reduce signal noise.

Too much green color


Problem solved. I tried playing DVD and the TV picture was fine. So I double-checked cable wires from cable box - one of the wires was loose (obviously it was the red color input). After tightening, the TV picture is good as new.

Sound stays on & picture goes to blank screen


I do not see any reference on this problem and I even checked with Sony. If you are on a cable box, I suspect that is the problem.
