Red Blue and Green?

blue is always in the middle and the green / red are on the ends. Black / white means you have the wrong matching cables. You need to make sure to match red to red, green to green, blue to blue.

The series of the cable should go green red blue into the back. if you put the green in the red and the red into the green it give the TV a red base to go off of for the picture so everything is red. The reason the green cable won't is because it transmits a black and white picture which allows it a nice base to add the green and red to.

**Keep all pairs together and you should be fine***

You need to also connect the RCA audio out (red/white) from your source to the audio input on the TV. You do not need the yellow wire as that is for composite video. The component cable (red/green/blue) is only for video. Look at the input on the TV where you connected the red/green/blue cable. Right next to it, you should have another red and white connectors for the audio input. Connect that to the audio out on the cable box.

The service manual on page 8 shows how to adjust the Red/Blue/Green screen voltages. To get to the adjustment board, take the front speaker grill off (two screws at the bottom left and right) and set it aside. No need to disconnect any wires. Then remove the plywood board with 4 screws that exposes the screen/focus adjustments. The top 3 adjustments are for focus, and you need not mess with these. The bottom 3 adjustments are for Red/Blue/Green screen voltage rough adjustments. My screen showed red lines, so I had to turn the bottom right adjustment with a philips head screwdriver just slightly until the red gun retrace lines where no longer visible.

Your picture tubes are trying to short out you have 3 red, green ,blue.

Are the yellow, red & white cables RCA phono plugs?

Yellow = Video
Red = Right Audio
White = Left Audio (mono)

The red, blue & green cables are for picture only and don't include sound. Have you tried using the red, blue & green for the picture and using the other cable, red & white for just the sound? Don't use the yellow.

Good luck!

need make and model

you might wanna look into the "flicker issue" with your set...If you've had it for a while a could be that it's just worsened over time and developed into a voltage leak. I have the same set and it went undetected for a couple of years due to poor quality cable signal..once I went to a clear signal (ie. directv) the issue was very noticeable, but by that time it had progressed. Eventually one of your guns will fail and the set will stop working all together (mine did just under 4yrs from purchase) and unless you have Sears warranty that WILL try to stick it to you. TRUST ME!!! Good luck.
