How is everything cabled? Is this over the air or using composite cables (yellow/red/white). Sometimes this will happen when you plug  a component cable into a composite connection or vis versa. If it's over the air signal or cable tv, check and see if the on screen menu for the tv is also in B&W. If the menu is B&W, it could something else.

Why does my KD-32FS170 32" Sony Trinitron screen have blue hues


If you turn all of the color out of the TV, the picture should be black and white. If that picture is not a true black and white picture, the TV will produce a color picture that has that behind it. It takes the proper mixture of red, green and blue light to produce white. This is something that is done inside the glass picture tube.
In your case, one color (blue is stronger) and the others are weaker.
It probably had not been used for a while. SOMETIMES, the weaker colors will get stronger with use. Adjust the brightness and picture controls to get the closest you can to a black and white picture, and then add the amount of color that seems right to you. Use the TV and hope for the best. It will improve, but 2%, 10%, or 50%; I do not know. The proper repair is to replace the glass picture tube, which is not an option at this time. So, turn it on, play games, and HOPE for the best.

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.

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
 transmission.
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.

Color problem


Please fine tune those B/W channels to obtain color picture. If TV is more then 4 - 5 years old, it needs resoldering in tuning area or might need replacement of IF block.

Toshiba Color Television....now picture is black and white


Good day.
The missing color issue can be resolved by resoldering the loose contacts in your units circuitry. Your unit is still worth to be fixed.

Response is highly appreciated.

No Color on my Audiovox AVT-1498


That model has a history of bad solder connections in various circuits. I would not be surprised if that is the case with the color circuitry. You may get the color to come and go by slapping the sides of the TV or lifting one corner about 1/2 inch and dropping it. If it does, it is a bad connection and possibly fixable. If no change is noted, it could be a bad semiconductor or capacitor, etc., causing the symptoms. For that size set, it would probably be cheaper to replace with a different brand. Toshiba has a nice 14" model IMO.
