It's possible the screen is damaged, or a tube has gone bad (is this an older tube TV/ not an LCD/Plasma/LED?).

Component (red-green-blue) 3 wire RCA will always have a superior picture.
Yes, but a component or HDMI connection will yield better picture and sound.
An RCA cable with composite video is better than standard definition cable. An RCA cable set (3 cables) can also carry a component video signal, which can be Hugh definition up to 1080p. Cable television can also carry a high definition signal if you have a HD cable box or a TV with a digital tuner. For connecting a VCR, an RCA composite video cable will give a better picture than the RF antenna cable.
Video is picture and audio is the sound. Home theater receivers have RCA composite or component, S-Video or HDMI for the video input, and RCA analog, Toslink (optical) or coaxial inputs for digital audio.
Check your cord going from your Satellite TV receiver to your television--if you are using a rca cord, the cord could have come loose.
There is no 'reset' button on RCA televisions of this size. Depending upon the model, there may be a factory default restore function in the menus that sets the picture and sound controls back to factory settings.
To watch Internet TV on your home television from your computer, requires a vga to rca adapter. The VGA end of the adapter plugs into the VGA port of your computer. The RCA end of the adapter plugs into the RCA converter on your home television. The RCA converter carries the signal to the television. The RCA converter is needed to watch cable or satellite. The RCA cables consist of three cables. All three cables work together to deliver the picture, left channel audio and right channel audio. Newer model televisions have the ports on the back of the television. Older televisions have the ports located on the front. These popular coaxial cables are included when you purchase a new television.
