My Emerson tv has a green tint.. How do I get it back to normal?

I would unplug it from the wall for a while and see if that will help reset it. Also make sure there are no magnetic devices near the screen because this will change the screen color as well. Mine will mess up every once in a while so I just unplug it while I am off running errands, plug it back up when I come home and it seems to reset itself. Good luck

In those sets there is what they call color wheel and it could be on its way out it sounds like its stuck.or not working prop in any case you need to bring it in for service place

My LG flatscreen image emits an intermittent green tint and then reverts back to normal colors

It sounds like you can have optical engine issue. That's if green tint was show up very gradually, until one day it really caught your attention.Normally some parts of the screen more green than other. It should get progressively worse. To solve this issue optical engine have to be replaced. It is pretty expensive repair if your TV is out of the warranty.
In case if tint appeared suddenly in one moment - you can try to check component cable connection on the back of your TV if you are using one ( green, blue and red colored). Sometimes it's loose or after disconnection people reconnecting it in wrong way.
Experienced tech will determine if optical engine is bad by running test patterns in special service mode. If green tint present on Grey scale - optical engine is bad.
Sorry for bad news.

Hi , I think thats is your green cathode in the picture
tube , the only way to fix that is a picture tube regenerator machine you will find that in a repair shop
thats a delicate operation...

Check 3.58 MHz color oscillator,, little metal can near large ic,
Also check color output transistors or any loose connections in the output stage

have you tested with another game?

maybe you are running a EURO game...the colors go crazy....it´s normal...try a usa version...

Good luck!

CHECK Q2A13 PART # 260P533010 ON THE RGB PCBOARD. ALSO CHECK Q6G02 PART # 260P696010 ON THE GREEN CRT.PC BOARD
IT COULD ALSO BE SOLDER RELATED ON THE GREEN CRT PC BOARD. LET ME KNOW IF YOU NEED ANYTHING FURTHER.

green tint & screen dark means that there is a problem in green video circuit. 1 check green video supply . 2 components in green video ckt. 3 adjustment in green video section. 4 check for signal to green video.

Loose connections in CTR board ( picture tube), resolder it.
