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...
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.
-Picture tube has become weak after long useage
-A fault with the automatic degauss circuit could be causing the color problems.
-The color drive circuits may be out of adjustment.
I don't have instructions for you on how to fix this, I would recommend you either buy premium assistance or contact
another expert with long tv experience to possibly get details
on how to correct this problem.
I would recommend you contact your dealer for repairs if you have warranty. If you don't have warranty it may be cheaper to ask around.
Hopefully someone on here has a manual and can tell you exactly where the tint controls are. Also need to try adjusting the color level, turn it clear down so you have a black and white picture.
Is the picture still green over the screen with the color control
set clear down to black and white? If it does, you might
have an issue with the green gun going out or problem in the
circuitry to it.
By the way, the best way to adjust the picture settings on a
tv are to first turn the color control clear down, then adjust
brightness and contrast for best black and white picture, then
bring up the color level to where it should be and adjust the
tint for best red/green ratio.
I just had a service tech out and replaced the color wheel. now i have the same issue with the color...the people all look blue. He told me that now the the digital board is bad. It's the board were all of the connections go. I'm not convinced, as I remember reading something about color settings needing to be adjusted after color wheel replacement.
I had the same problem with my refurbished HT-30744 model and my mom's HT-32744 model. It was either try to fix it or buy a new one, so I figred had nothing to lose.
I removed the back cover, unseated the picture tube driver board from the neck of the picture tube (it just pulls off), put on a dab of di-electric grease on the connector on the card, reseated the card, removed and re-applied more grease, reseated the card and the picture has like new for 2 weeks now!
The first thing I would check is the antenna or cable connection into the set.
When an analog TV signal is weak, the first thing to go is the color, then the picture, then the sound.
If you have another TV, connect it to the very same cable or antenna connection and see if it fails the same way, too.
Make sure you just disconnect the cable end right where it goes into the failing TV and connect it to the other TV - don't disconnect the antenna cable from the wall for this check.
If the second set does not fail, gently pull on the antenna wire - not too hard, you just want to put a little tension on it to see if it makes the color cut out.
Reconnect the first one and try again. If it's fine now, the connection was loose. If not, it has a tuner problem that must be repaired.
Also, when you look at the end of a TV connector, the center wire should stick out just a little bit, like in the attached photo.
If it doesn't stick out as bit, it won't make good contact, and will result in a weak signal.
