I have a JVC l'art 32" T.V. Model #AV-32FA44. I now have a problem with a green hue invading the screen from the left side. It only takes up a small part of the left side of the screen. It appears sporadically, seems to fade away, and then returns. Is this a precursor to big 'tube' problems..

What you are seeing is called the "Green Bleed".

Call several servicer's and get an estimate on repairing the problem.

If not above.
Any big speaker or magnet near left side of TV? It could be a component with a thermal intermiddent, bad, cracked, or cold solder connection also.
