Im trying to upgrade to component cables (red blue green) and i have a picture and sound on the screen but its blue. the cables are hooked up properly and are secure. any suggestions? besides throw it away

More info would be nice. Are you using HDMI or Component cables. If it is component cables (red, blue, green for video white and red for audio) Check your red and blue connection. Green alone will give you a black and white picture. If you are using an HDMI cable, replace the cable to see if this changes anything or if you have another tv swap cables to see if problem stays with tv or moves to another tv.
If the problem happens using different input and devices, then it is either the terminal circuit (input/output connectors) or the processing unit in main board. The terminals are unlikely the culprit if problem concerns different inputs.
I imagine that the picture is not properly B&W (gray-shades) but some kind of reddish, bluish or greenish picture as the LCD will process picture using RGB (red green blue) channels instead of CYMK (cyan yellow magenta black) like CRT TVs.
Test the TV using an external aerial. You will notice if the channels have the wrong color even from static.
Use different inputs, different cables and different devices. beware of SCART cables, the SCART contacts are very easy to break. A defective cable will loose picture. Better testing using AV cables and component cables. AV cables are red/white for sound and yellow for video. If the two-wired yellow cable does not work, then the TV is faulty. Other test can be done using component cables. Component cables send the three red-green-blue signals on different cables, hence testing is simple. Test swapping cables and see if TV tone stays the same if color tone changes the problem were the cables. Test also using at least two different devices (e.g. one DVD player and one TV receiver or a playstation).
If you find that the TV is defective call the manufacturer at the number listed on manual. If the problem is that one or more RGB channels do not work the TV main controller board must be replaced.
Make sure that the unit is connected to the tv properly. Be aware that most dvd players have six connections. You can connect the unit to the television using RCA cables (yellow, white, red) or RCA sound with component video (white, red, blue, green, and red). When using the yellow-white-red method, the sound is carried by the white and red cables and the video signal is carried by the yellow cable. If you're using the white-red-blue-green-red method, the white and one of the red cables carries the sound, and the blue-green-red cable carries the video signal. This connection uses one cable for the green component of the picture, one for the blue, and one for the red. Make sure that the cables are connected properly and you don't have the two red ones mixed up. Connect Sound-R to Sound-R, component R to component R, etc. If that doesn't work, you may be able to adjust the picture on the tv. There's still a chance that the machine is defective.
Good day sir, your inquiry about the green lcd screen can be caused by several things. 1. The monitor/tv produces 3 colors, red green and blue, the tv mixes these three colors to produce the picture. a loss of red and blue produces this green screen. so check the cable, specially the red and blue jack of the component inputs, and the red and blue cable. 2. there may be loose contact on the signal cable. try using the video input instead of the component input. 3. the dvd player may have the problem, check the player component out jack. a loose jack port can cause these problem. hope this may help. thanks
Looks like you are using Component cables. There are five cables. The first three cables are Green,Blue and Red. These are the ones that are molded next to each other and are the Video signal cables. The other two cables are Red and White and they are the audio cables.
First to correctly hook up these cables you need to Connect (Match) Color for Color. (Green to Green, Blue to Blue, and Red to Red. To tell if you have correctly connected the Video cables is to look at the screen. If the picture looks ok (Normal with no colors missing then you have connected the video cables correctly). If you see a missing color meaning red, then switch the Red cables. The picture should be ok now. The remaining two cables are the Red and White cables. The "Red cable" is for the "Right" audio input and the "White" cable is for the "Left" audio Input". If all is connected correctly then you should have a good picture and Left and Right audio.
The red white and yellow cables are composite connections. The red/green/blue connections are component connections.
The playstation's composite connections consist of two audio connections- red & white, and a composite yellow video connection. The TV's white connection is the audio, and the red/green/blue are component video. You need an adapter that will connect the one yellow(composite video) to the three red/green/blue (component video) connections
RCA cable connectors (red,white, yellow) are usually for an analog setup. You could still use these for "component" setup, but know the difference with color stamps as follows:
Component color stamps are "blue, green, red" ( blue is marked Pb, green is marked Y, red is marked Pr)
RCA color stamps your using are "red, white, yellow"
Here are the proper hook up method for "Component" using your "RCA" connectors:
On both the TV and DVD component setup:
Plug the red RCA fitting in the component port marked "Pr (red)
Plug the white RCA fitting in the component port marked "Pb (blue)
Plug the yellow RCA fitting in the component port marked "Y (green)
Be sure this setup is the same for the TV's component input ports, and the DVD's component output ports.
i-Note:
For optimum picture quality you may want to purchase component cables as the gage is thicker giving better impedance match resulting in better picture and sound quality.
