Greeish Tint Color

My JVC AV-27S33 has a greenish color on every channel. I tried to change the color setting with the remote and the tint but it didn't seem to improve. This TV is going on 5 years now and hasn't given me any problems til now. Any suggestions on how to fix this is appreciated. Thanks in advance.

    ctf1800,

    Are you referring to the tv model as well? Or just the color? Because I am having issues with my JVC AV-27S33.

    And if your referring to the color on that Philips in the pic then the answer is no. It has a greenish color to it on all channels. I will see if I can get my hands on a camera to take pics of it. Thanks.

    Here is the pic. I think I uploaded it on the wrong place. Here is the link to where I initially uploaded it the first time.

    I have the same problem, but my TV has a red tint to everything. Black & white pictures appear as sepia color.

    Any suggestions how to adjust color other than the standard menu corrections, which I've tried to no avail?

    I also have the dark picture as described on another entry. Pictures depicted as night time or in dark locations appear as a virtually black screen. Using the onscreen menu, I've set the picture at the brightest setting. Still can't see night scenes.

Have you move the tv or is there a speaker that you might have move close by the tv?

turn the tv off for an hour and turn it back on see if the degaussing can correct ir other wise it may have a bad connect on the degaussing or you have some kind of magnetic device close by.,

    Looks like the red gun is missing, you can look or tap on the circuit board that attaches to the picture tube (don't tap to hard you may break the tube) to see if it has a loose connection, otherwise i would look for the red output transistor bad.

Try a different video cable or make a careful inspection of the pins in the video connectors. Look for bent or missing pins. Your missing a color channel.

JVC AV-27S33 only displays black and white (Color gone) Menus are still in color!


Check its color system adjustments. It will be best to make a factory reset to this set. Just unplug the TV from AC mains wall socket, and re-plug it after 10 minutes of so. This must make your TV a hard reset. If this do not help you, the chroma section circuits of your TV need to be checked for fault/s. This is a skilled work, and it will be best to contact any experienced service technician.

Green tint


Go to a channel that is in black and white and turn color all the way off.

Screen should be a black and white or gray color.

If green there is a fairly easy way to adjust--let me know what you find and I will tell you how to attempt the adjustments.

Color is a problem. Screen picture has greenish


well it seems you have an issue with one of your video boards, it could be that the Analog Video Board (the one with the inputs and outputs) is partially damaged, but it can also be your Digital Video Board, which is the one that projects the image

Take time to get used to the settings, you may think the screen looks dull at first. The truth is most people have way too much contrast on their TVs.
These settings will also work for Cable or Dish hookups, in which case you may change the Noise Reduction option to Medium to reduce signal noise.

I've found several bad solder joints on the neck board of my JVC 32' leading to the exact same issues as yours. Inspect the Driver resistor solder on the neck board.

A constant red tint problem (AV-56P787)


This is an indication that the red gun is being driven too hard. Have you tried to adjust the red color control? If not try this first and if the control can not adjust the color then you will have to find out if the control grid on the red tube is working and has the proper voltages present. Which you will need the following equipment to do. Multimeter Oscilloscope Along with these you will need a schematic to show you what the signals and voltages should be. And I might also suggest having a pattern generator and using the color bar signal since more then likely that is the one being used in the schematic as the reference signal.
