CRT green gun is not working properly , maybe dry soldered or no green drive signal. Pink and red colour is due to missing of green colour.

    This problem can be fixed by complete soldering in crt board. And then check it out by observing symptoms

My flat screen Sylvania TV is flashing different colors what's wrong


Better late than never. The problem is that your TV is in the service mode. There are many ways this can happen. But, lets just get down to fixin this! With the original remote and the TV on. If the TV will not shut off, do this. Press the left cursor button on the remote, followed with pressing the right cursor. Power off the TV with remote, or press off button on TV.

Secondly, your TV will power on and off. But you have flashing colors. Do this. With the original remote and TV on. Press the up cursor button, on the remote, followed with pressing the down cursor. Power off TV with remote, or press off power of TV. Thanks for asking me, Matt of Martins TV Repair.

Its glittery white because i briten the color but when darken it gets green


you must re-adjust in the RGB (Red-Green-Blue) setting. depending on the brand of your TV, because there are set manually from the TV (you must open the cover of the rear of the TV). and there is a set directly from the remote only, with the open "factory settings", then you can re-adjust RGB color, especially green, not too dominant with the other colors (RED-BLUE). how to set is that you need to neutralize the color, (color TV sets to zero level) so that the image becomes black and white. if the green is too dominant, then Decrease the level of Green Bias or Green Cut off/ G-drive.

Dominant blue


Can you post to the party who has too much green how to adjust the video adjustments? They need to know so they can see if
its just a simple adjustment.
In your case, first turn the color level clear down to where you
have a black and white picture. As in the case of too much green,
question is if the picture is black and white or if there is a color
on the screen so its blue and white? I suspect it will be which
is typical when the guns start to fail. Likely the green and red
guns are weak in output. There are screen adjustments in the set that a tech can set up that may help some, but the only real fix is to replace the guns which is expensive and requires a complete allignment. All 3 guns need changing to get it back to spec and it is a good idea to replace the flyback for reliability. Get an estimate and likely you can replace the set for the same money.

Color sudden change


Good day.
Your unit is still worth. It may be a caused of loose contacts along the circuitry. It can be remedied by resoldering the terminals particularly the chroma section and the crt circuit.

RCA CTC203 no red colour


Did you change the resistor by yourself? I am not sure if your TV has manual adjust on the back of the TV that you can adjust. Some times turning the TV Off and unplug it from the wall helps because it resets the TV. Check your Back ground color and see what is the dominating color. Blue, Green or Red. If this doesn't work please call a professional to look at it.
