I have purple tint running up both edges from top to bottom on my 36" RCA t.v. ... What is causing this ?

Question

The tint will go bad, but just on both edges of the screen. It is not constant but comes and goes.It is always purple in color. It may last 30 seconds or so, then goes away. Then it will come back in a few minutes and so on and so on...

Answer 1

some of those old monitors have a deguass button or degauss function in the menu.

It's a build-up of magnetism.

Try that.

Answer 2

Move any speakers or other magnets away from your screen.
