Our new dynex is only in black and white

The problem is the color processing ic or the crystal that locks the color on frequency. The set should be returned for exchange.

We have a Philips Magnavox Model #TP3284C101 TV and plugged in a Durabrand DVD Model #DVD1002 player to it. It will only play in black and white on this TV. But when we plug the DVD player into another TV...

It sounds like you have a standard problem.
Is the TV you are using, that gives the black and white picture, the same as the other ie, both NTSC or PAL and both on RGB or Y-C or S-Video?
Check to see what is required and set the DVD player accordingly.
Hope that helps.

JVC 32" D series TV is suddenly black and white

Wow that's interesting, was there anybody watching your home while you were gone? There is a possibility that someone simply turned down the color level with the color control? Check that first. It's an unusual symptom. With composite video, component video or HDMI it's not usually possible to experience that defect. Since the color (chrominance signal) is usually inseparable from the luminance (black and white signal) I would check the color setting first. Other wise your set has become unable to detect that color signal... I bet it's a setting rather than a defect.

Happy Viewing

When I turn my TV on it plays just fine for about 10 minutes. Then it goes to black and white. If I turn it off for a few minutes and then turn it back on, the color returns for a few minutes and them goes...

The tube harnesses may be a little loose and when tube warms they short. Try adjusting the wiring harnesses. (Only attempt to do so if you have electronics knowledge.)

Picture is now black and white

 First, confirm that the source is actually in color - try another channel or input device.
Next, check the settings of the color control - it may have accidentally been turned down. If your TV has some kind of automatic picture mode, try turning if off and adjusting the color control. Try adjusting fine tuning if you have such a control and the problem is with a broadcast or cable
At this point with a confirmed color signal source, there is a problem with the chroma circuitry.
Note that to the average person, the obvious question becomes: is my color picture tube bad? The answer is a definitive NO. It is virtually impossible for a defective CRT to cause a total loss of color. A defective CRT can cause a lack of a primary color - R, G, or, B or a short between two colors which will mess up the color but is not likely to result in a black and white picture.
Some possibilities in no particular order:

  1. Weak signal or defect in tuner/IF causing loss of signal strength.
  2. Coler killer set too high (internal control) if it has one.
  3. Defective part around the chroma chip/circuit. Faulty color oscillator.
  4. Bad connections in area of chroma chip/circuit.
  5. Defective chroma chip (don't suspect this first just because it is probably very expensive).
A service manual or Sams', DMM, and scope will help greatly in attempting to troubleshoot this unless it is an obvious bad connection. Try prodding the main board around the chroma chip with an insulated tool to see if you can make the color come and go.
I had one set where a $.02 resistor decided to open up causing just this problem - perfect BW picture, no color. Another had a coil with a broken wire.

Green tint I can't seem to fix

Hopefully someone on here has a manual and can tell you exactly where the tint controls are. Also need to try adjusting the color level, turn it clear down so you have a black and white picture.
Is the picture still green over the screen with the color control
set clear down to black and white? If it does, you might
have an issue with the green gun going out or problem in the
circuitry to it.

By the way, the best way to adjust the picture settings on a
tv are to first turn the color control clear down, then adjust
brightness and contrast for best black and white picture, then
bring up the color level to where it should be and adjust the
tint for best red/green ratio.
