Recently the picture on this TV 'went out'. Kind of hard to describe
but I can see red colors but nothing else. I tried using the 9-point
convergance and all three of the colors came on and went through their
routine. Occasionally the picture will work ok but most of the time it
does not. One additional point, when I hit the menu button (at which
point the picture shrinks and the menu pops up) the menu items appear
to be 'washed out' but the picture looks ok.

This sounds like a typical problem in the sweep power supply. There is a filter capacitor for the CRT screen voltages that is most likly open or changed value. The first clue is that you get all your colors on the convergence. This is a high voltage circuit and should not be messed with by the user unless they have solid state repair exoperience and know all the high voltage saftey factors involved. Please call in a trained tech to assist you in this matter. Good Luck Let us know how you made out please.
