My Tv playes OK then the screen changes to pink & red. It will be this way for awhile, then change back to a normal screen. I did all the adjustments, but it still changes back and forth. I tightened all the cables, and even tried putting a wedge under it. It will be good for awhile, then change. Any ideas? Thanks

There is a coil in the set with a magnet glued to it, called the horizontal linearity coil. Sometimes the coil "sings", making a squeeling sound. I have seen this many times, and there really isnt anything actually electrically wrong with the set. To stop the squeeling the coil should be replaced.
Probaby the stereo decoder IC went bad or a supply voltage to it is too low or noisy. If it has audio output jacks on the back of the TV, connect it to an external amplifier and see what that sounds like. If it is ok in stereo or mono mode then the amplifier in the TV is bad. This will prove that the stereo decoder is ok.
On your remote should be a button called TV caption or text. Turn off the closed caption as someone hit it and turned it on by accident. If its not on your remote, then it is in the menu. Good Luck
