When I hook up the cable to the RCA truflat tv the screen stays blue. I had it working with a cable box, do you know why it's not working with just the cable?

Your cable system is probably digital, and the tuner in this TV isn't compatible with the system. The cable box output was a regular TV channel 3 or 4 signal the TV could tune in. Without the box, though, your TV's tuner sees nothing. You'll need to stick with the box.

Green picture only

The projection TV has 3 guns RED GREEN BLUE. In your case the red and the blue guns are gone. So you are getting the green color screen. You got to replace the picture tube.

Rca tru flat tv has a red picture

Is your video input (from cable or satellite or fiber optic, etc.) coming from a coaxial cable, a component cable (red, green, and blue connectors), or an RCA cable (yellow connector for video)?

If you can, try an alternate input method and see if that makes a difference. Does it happen when watching DVDs or tapes, or when playing video games, or just when watching television?

Blue line

good day.
The case you encounter with your unit is just a minor one. Most often caused by loose contacts particularly in the horizontal circuitry. Try to have the circuit be resoldered.

response is highly appreciated.
