That isn't convergence that does that. There are "screen" trimmers, if someone has messed them up you can get all one color, but the usual cause is the picture tube going bad. The screen trimmers are on the PC board on the gun (narrow) end of the CRT. Some trimmers are color drive and others are color black level, or "screen". Don't adjust the color drives, it is a delicate balancing act to get them right. Find the one labelled blue and turn it down. If all you can get is too dark, turn the red and green up, just enough to see a dim color haze in a blank picture. Balance them out so the haze is gray. Then turn them all down just a hair so the screen is just black. Then try a picture. If you can't get gray on a blank screen then go to the high voltage transformer (the one that can kill you if you touch the wrong part) and adjust the "screen" control on its side up (it adjusts all the colors together). If you still can't get gray, one or more of the color guns is weak, and you may as well chuck it.
Of course it could also be a bad blue drive transistor, but fixing that takes more expertise than you can get from a forum.
Actually, just getting the TV open and propped up so it doesn't fall over is a job in itself...
How long u have this RCA analoge tv?Around 10 years or more and used it like about 5 or 6 hrs everydays?Yes,than ur tv it is losing CRT tube radiation cohetion.As times go bye years in years out the tv CRT-(tv tube) radiation will slowly dying out,Tv actual pictures will lost some of it luster and it brightnesses to the tv auctual pictures.Brightnesses of CRT tube will get darker and darker until the tv actual pictures barely it is watchable anymore.Contrast,Brightness and Colors adjusting more will help some.But u have to take this tv aparts and take a Flat scerw driver turn up a little bit more of the tv HV-(high voltage) SCREEN button on the FBT-(flyback transformer) to make any big differences of the CRT tube brightnesses.The FBT-(flyback tranformer) is the big block of plastic with a red wire with a black cap hook up to the tv CRT-(tv tube).This adjustment on of the FBT,HV-SCREEN button will help the tv CRT-(tv tube) last another year or two.

Go to the menu screen and look for picture options and then look for color or Hue on the menu, this will allow you to change the hue and correct the color balance. I have a Sony and there is a yellow button on mine and it changes the settings to what they call Cinama scene and when I press this it makes the picture darker and more yello. Mine is a Sony and yours may be different.
yes! those are the screen and focus adjustments. 3 for screen, 3 for focus. try this. go in menu....turn down color, brightness, contrast all they way down. you should then have no picture, but in your case a little red. then go to back of tv and turn those 3 screen adjustments all the way down. slowly turn the screens back up until you get barely a picture. because remember, your brightness and contrast is all the way down. the picture should be dim but seeable and with red, green, blue adjustments, make it a black and white picture. when balanced..... turn up color , brightness, contrast in menu. enjoy!
Adjusting the picture tubes is a scary proposition, but since you have already done it...
The easiest way to balance the gray scale is to turn the color all the way down on the set. The next part is easier with two people if the screen controls are on the back of the set. This is the part you saw that has six small knobs on it. There are control for the focus of the red, gree and blue and for the screen level of the red, green and blue. You will want to adjust the screen controls in an effort to get the picture black and white (this is why you turn the color down), hence the term "gray scale". Just make slight adjustments, take your and be patient. It will take some time, but you will get your picture balanced back out in time.
use the advanced options page and reset the factor blue and red convergence defaults then do re apply the auto color defaults color at first it seemed very red (which is good because red was the missing factor in the green picture) but after reseting all the color and tints to the normal ranges I then reset the color auto correct again and all seems fine.
They should be adjusted to set voltages. however it is best to shut the color level to the lowest setting then try t balance the screens to achieve the best black and white picture. then turn up your color level. Your brightness level should also be set to 50 % then when you adjust for the best B&W picture. You will have better color and brightness when you reset your color and brightness levels. Hope this helps.
