Good picture but no color

I have a good picture but it has no color. All the menu's are in color but the picture itself is black and white. I have tried all video inputs and antenna inputs and still get the same. It will flicker with color if I bang it on the back or side. lol What would be causing this? Thanks ahead of time.

    The problem is not in any menu's. There is something loose inside. Like I said, when I bang on the side of the tv, the color will flicker on and off.

Check in the TV settings menus for the color mode. Other tvs have the option to the output to either black and white or color.

You may have to go into the service menu to get this working

Let me know if you need any further help

good luck

Hi,

Initially, have you tried a full hard reset? If not, pls unplug from the mains. Most current devices would reset and revert back to factory default settings (assuming no internal hardware fault) when unplugged for a considerable period of time (from a few minutes to a couple of hours).

If the above does not prove to be corrective, you may have to consider:
1. demand service from an authorized service center if the unit is still under warranty;
2. seek onsite services of a qualified professional; or
3. consider a DIY (do-it-yourself) which would require access to a service manual or at the very least a schematic diagram, familiarity with electronic components and circuitry, a DVM and possibly as soldering iron.

From initial search, it would seem that this is a common issue with some Toshiba models.

Hope this be of initial help/idea. Good luck and kind regards.

Thank you for using FixYa.

There is a loose contact somewhere in the color circuitry of your TV. Specially where the color oscillator is or it could the 3.58 Mhz Crystal that is defective.
A cold/crystalized solder joint will cause this failure too.

Poor viewing quality


By poor color quality, do you mean that if you turn the color control all the way down, the black and white picture is more like black and red, green or blue - or do you have a good black and white image? If the B&W image is good, and the TV is an old (8+ years) one, maybe the mirror inside the set needs a good cleaning - especially if there are smokers in the room. If you have a B&W picture that is tinted, then you may have to go into a service menu to adjust it back to a better picture. Hard to guess the problem without more specific description of symptoms.

What is a good Microwave Leak detector - make  absolute measurements? Can a cell phone be used to detects leaks from Microwave ovens.?


I replaced two convergence chips the resistors were all fine. This took care of the 3D look. I also replaced the coolant in the blue and green although it was the blue which was badly contaminated. The picture is now clearer than before but I am unable to get color. I can see vibrant colors when I pull up the TV's menu. I can see the colors in the convergence menu as well but no color in the picture. The color controls only make the picture brighter or darker. It is sepia in color not black and white. What could this be?

Having problem with getting the color and contrast right?


Good Day;
Turn your color down all the way, do you get a good Black and White picture with good black, white and grays? If not your picture tube may be going bad. It can be adjusted sometimes to get a 'better' picture.
If picture is a good B&W; adjust britness level: 50% > contast: > 90/95 % >color: 50%.
Good Luck, big IRISH.

Bad color


Turn the color level all the way down and see if you have a good black and white picture. If your screen isnt black and white it should have a predominate tint to it. then turn the screen control for that color down to achieve the best black and white picture. then adjust your color level that should help.

Red , Green And Blue.


Heres the best way to set a phillips screen controls. Go into the picture controls and set picture or contrast to roughly 75%, then set brightness to 50% and then set the color level completely off. Then adjust the screen with the 3 color controls untill you recieve the best black and white picture as possible. If you are unable to achieve a good black and white picture change the coolant in the green and blue tubes. But if you can get a good black and white picture stop there then turn your color level back up and the picture should be correct. Let me know if you need further assistance.
