Hello
Just make the picture status button on the remote control and get the display setting to its factory mode.
The VIDEO STATUS button gives you a choice of three TV picture display settings, including a
display of your own preferences.
Standard - Resets the picture display to the factory settings.
Dynamic - Heightens contrast.
Theater - Gives a rich, film-like look to video. (AV-27D303, AV-27D203 and AV-20D303 only)
Sports - When you watch a sports program. (AV-27330, AV-27320 and AV-27S33 only) Press the VIDEO STATUS button repetedly to get these choices.
In that case does this color problem occur on all inputs? If not then please make sure that the connections, especially the red connector, are clean and tight
Press Menu on the remote Press Up or Down, Ch + or C- to get to Closed Caption Press right side button or Vol+ and Mode will be highlighted Press right button or Vol+ until it says Off on the right hand side of the Menu Press exit and that should do it.
The black box your are seeing on the screen is the box to display text. It is listed under your "cc" closed captioning setting as T1, T2 etc. Go into your closed captioning and shut off the text. You can still leave closed captioning on or off. The text system was never really used but they put it on all of the TV's.
Repaiur or replacement? It's Your call! If you know Solid State repairs, then worth a try. Most likely a bad Electrolytic capacitor in the Vertical Oscillator / Output section. Do not waste time identifying faulty one, but change all at one go. Even if one is faulty, the others must have started drying up, and will cause problems in the future.Remember "An Ounce of prevention is better than......"
How old is the TV? More than 6-7 yrs? Then it's time to do a trade in.
But if you are very attached to it, get a Technician to recondition the Picture Tube. This may give it life for another couple of years.
You could also ask a technician to check the DC filter Capacitor for the HT line to the Video Drive circuits. Over time this capacitor dries out and also causes a darkening of the picture. It is normaslly a 100 mfd 160V capacitor.
