If a standard TV has color splotches in 1 or 2 corners of the screen, it is possible that a large magnet, such as a large speaker, is or was near the set and has magnetized the picture tube. The set has a built-in degaussing coil but it is small and will only demagnetize small magnetic fields. Make sure there are no magnets near the set and if the colors are still off, have the picture tube demagnetized with a strong portable demagnetizer. As for the audio, when there are audio output jacks on the back of the set then there is usually an option to turn the speakers off. Some sets have a switch somewhere and some sets have a setting in the audio page of the on-screen menu. Look for a switch or go into the menu, navigate to the audio page and look for a speaker setting (ON / OFF) and make sure the speakers are set to ON.
