Hello edgarhelen1,

This could be a problem with the Red tube (Grid to Cathode short). I would suggest that you have the tube checked. However if you have a CRT tester you could do this yourself. I any event this sounds like a CRT issue.

The color is screwed up


The projection TV has 3 color guns that focus to produce a single image. The 3 colors are red, green and blue. It sounds like the blue gun went out. You should be able to remove the back panel of the TV. If doing so, use caution as there is a mirror attached to the back panel. Once removed, you can confirm that the gun is not working. The fix, unfortunately is neither easy nor inexpensive. The problem could be simply a poor connection to the circuit board up to needing the replacement of a new light or perhaps a new gun. Unfortunately, there is no magic button to press and nothing you are doing wrong. This is a very nice TV and it may be worth getting an estimate to repair it. Or, perhaps this is a good excuse to go out and get a new 50" plasma! Hope this helps. If you can think of anything else I should know, please comment.
