My TCL TV picture is distorted with lime green images in the picture..what does that mean?

A green tint to a tv means it's lost its red channel (may additionally be blue channel). Check that your video cables are connected fully. If that's not the culprit, and changing tv settings doesn't work, you'll need to take it to a repair shop; so they can repair the "red circuits:" Note: there aren't any "red circuits" per 'se, but there are circuits that tell the various computer chips - in the tv - how to handle the image. By "red circuits" I'm referring to these.

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

As TVs age, the rate at which the CRTs begin to decline in terms of light output increases. If you go into the customer menu and adjust the color setting to zero. ( no color) observe the image. Is it good gray scale? Or, is the image still green tinted? If so, its definitely a problem with the CRTs( picture tubes) You may need to just re-adjust the screen settings for the CRTs or it may be more serious, a CRT may be bad. Replacing the CRT is a job for an expert and will cost $500-700.

If the problem is not the connections, try adjusting the tint on your television. A high tint setting will usually create a green
image on the screen where as a low tint will create a more red hue. In order to access your television's tint:
1. Press the “MENU” button on your remote control and use the LEFT or RIGHT arrow keys and select the
VIDEO menu.
2. Then use the UP and DOWN arrow keys to highlight PICTURE SETTINGS and press the "ENTER" button on
your remote.
3. Next use the UP and DOWN arrow keys to highlight TINT then use the LEFT or RIGHT arrow keys to adjust the
TINT. If the picture is too green the tint will need to be lowered.
4. Once you have adjusted the tint to your liking, use the DOWN arrow key to highlight DONE and press ENTER. The toshiba customer service telephone number is : 1-800-631-3811. I hope this helps you with your problem.

Probably a bad picture tube but I would need more information like Brand and Type.

Check the cable connections and/or replace the cables to the AV2 input.

If replacing the cable doesn't provide a solution, try running your DVD through the input. Since it works fine now, you would be checking the input AV2 by putting your working DVD. If the DVD plays with no problems, the input is fine.

Also try the VCR using coax into the TV instead of RCA into AV2. This will give you some idea about the condition of the VCR.

I suspect either the VCR or the cables.

Turn down your color and see if the screen has a normal black & white screen. If it doesn't then the CRT is bad (picture tube). If it is black & White then you have a either lost your red or blue.That problem will be in your video driver circuit of which a service center can handle.

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.
