Check the chroma IC for red output.

Your TV is in the protection mode. First, locate the horizontal output transistor. This is found very close to, or next to, the horizontal output transformer (also known as the flyback). The flyback should be on an aluminum heat sink, or on the side of the metal chassis. Disconnect or unsolder two of the three legs of the transistor. Measure it with your meter, or plug in the set with the light bulb attached across the fuse.
If the transistor is shorted, or the light bulb doesn’t glow bright anymore, replace the transistor and plug back in. If the light bulb glows bright again, you must replace both the flyback and horizontal output transistor simultaneously. In some cases this will fix the set, but sometimes there are multiple problems with a set.
Go to where the flyback is, and start measuring the diodes and capacitors on the flyback itself. If you don't find any shorts there, it could be a shorted vertical output IC, a shorted sound IC, a shorted disc capacitor in the Hi Voltage/sweep circuit, or in rare cases, a shorted capacitor or tuner.Feel free to ask and post whatever the result of your troubleshooting..

Hope this may help;

The DVD player should have come with a cable with red, white,and yellow ends on it. Plug these into the corresponding color plugs on the back of the DVD player. Then find the same colors on the back or front of the TV. They should be labeled "INPUT" or simply "IN" and they should be grouped together. The next step is to cycle through your inputs. There should be a "TV/VIDEO" or "INPUT" button on the TV orremote. Some sets just make you channel down all the way below channel 1 and the input appears there. If your set changes to the highest channel when you go below 1 then yours isn't like this. Anyway, at this point you should hear and see the movie you're trying to play if the DVD player says it is playing. If your TV does not have a yellow plug then it must be very old. You will need what is called an "RF modulator." This will allow you to plug in the three colors to your coaxial "screw-in" connection on the TV and you will tune to channel 3 or 4 to watch the video just like a VCR. Check any electronics store for these. Good luck!

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

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.

It sounds like the closed captioning background.

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.

Hope this helps.
