My rca hdtv has 3 split screens

if your supplying an RGB signal to this set from a cable or sat box and not using its built in digital tuner id check the connections of the "R" (red) cable input this might have come disconnected

check the connections in the back of the tv. If you are using a cable/satellite box, what sort of cable connects it to your tv? If HDMI then you should have sound and video thought that one cable. If component (5 plugs in total red,green,blue, and audio red/white) make sure the red green and blue plugs are seated in all the way on both the tv and the cable box.

In the old school standard AV: Red and White are usually audio channels (Red:Right - White:Left), Yellow is video.

Orange can be coax audio, (both L&R channels in one cable). Before digital (optical) came out, some receivers actually had a coax (orange) jack in the back. Radio Shack sells a splitter if necessary.

In higher resolution systems video is separated into three colored cables: RGB or Red, Green, Blue
called 'component' video. The green cable carries Yellow, the blue cable carries (PB) Blue and the red cable carries Red (PR). And with today's tech, the component signal is carried YCBCR as (digital video.) cf. http://en.wikipedia.org/wiki/YPbPr

Component 'wire colors' are there just to remind us. If your TV has "Component" input. Try green to green, white to yellow and black to red. Orange to audio (splitting L&R if necessary)..

Good luck !

Do you have a cable box going to the TV and is this condition on all of the inputs or just one. Chances are you have standard video connection plugged into the component inputs.

If you have a (yellow/red/white) cable make sure you have it plugged into a connection on the tv that matches those colors because if you have a standard video (yellow) plugged into the Green then you will get a black and white picture.

If you are plugged into a component connection you will need a total of 5 RCA style wires. One will go from Green to Green, another from Blue to Blue, another from Red video to Red video, anther Red audio to Red audio and white audio to white audio.

The common mistakes made with this connection is the reversal of the RED video and RED audio which will cause the humming noise you spoke of as well.

Thanks,
Robert

It depends on what kind of inputs your TV has; here are a few of the most common, all of which your DVD player supports (best quality first):

1) COMPONENT VIDEO (Red, Green, Blue)
If your TV has three inputs for video colored red, green, and blue, this is your best bet for quality video from your DVD player. You may need to buy a component video cable from the store (somewhat pricey, but great quality) which consists of three cables (again, red, green, and blue) stuck together. Just plug the red/green/blue cables into their correspondingly-colored ports on both the DVD player and the TV.
That covers your video. To set up audio, you just need some regular red/white RCA cables. On the DVD player, plug the red/white cables into the correspondingly-colored audio out jacks NEAREST to the red/green/blue cable you used earlier for video, then plug the other end into the audio in red/white jacks on the TV.

2) COMPOSITE VIDEO (Yellow)
If your TV has a yellow input for video, just use a regular yellow RCA cable. Plug it into the yellow video-out jack on the DVD player, then plug the other end into the yellow video-in jack on the TV.
To set up audio, you just need some regular red/white RCA cables. On the DVD player, plug the red/white cables into the correspondingly-colored audio out jacks NEAREST to the yellow cable you used earlier for video, then plug the other end into the audio in red/white jacks on the TV.

3) COAXIAL JACK (Antenna port)
If your TV only has a coaxial jack that you currently plug your antenna or cable line into, you'll need to buy an RF modulater and a short length of coaxial cable (you can find these anwhere: Walmart, Radio Shack, etc).
Plug the RF modulater into an electrical outlet, then plug your antenna/cable line into the "antenna in" jack on the RF modulater. Take the coaxial cable that you just bought and plug it into the "antenna out" jack on the RF modulater, then plug the other end into the antenna/cable jack on the TV. The RF modulater should have a switch on it somewhere that sets either the number 3 or 4; depending on which number you pick, that's the channel that your TV has to be switched to to view the DVD player.
Now you're all set to connect to your DVD player. Just follow the instructions in section (2), only now you're going to plug your cables in the RF modulater instead of the TV.
(I hope this wasn't too confusing; it really is a lot simpler in practice than it is in explanation...)

What are you splitting? Coax - just split the out to tv line. A\V cables or componet cables you'll need to split all wires (a\v- yellow and at least white, red to if you want stereo. componet- green, red, blue for video and red and white for audio.

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.

What cables are you using to connect to tv?
There's
1) Yellow and Red+White
2) Red+Blue+Green and Red+White
3) HDMI and Red+White

Cable Couplers
1) 3002 and two 685 rca rgb coupler f/f + rca coupler f/f
2) 3002 and two 685 rca rgb coupler f/f + rca coupler f/f
