It looks like the three color guns (if that's what they are) have gone haywire. It was working okay, then suddenly the green, red and blue are curving in different directions. I tried the alignment setup but it doesn't work, because the problem isn't uniform throughout the screen; I've got a bulge in the lower left where the green curves upward, with the red and blue curving less so. They're also curving across the top. The only place the picture is fine is in the middle. Bottom left two-thirds have a big red swath, with graphics appearing double and triple.
Is there any hope for fixing this, or should I just figure it's been a good 9 years and scrap it?

you have most likely lost 2 of your color guns, most projectors have RED, Green and BLUE as the projector colors (some newer projectors have added a 4th color). if one of your color guns has gone out, you may experience colors that are not correct. that is where I would start. go to the convergence routine, in your setup menu. this is where you can determine if one of your "guns" has quit working.
you may have a dead or bad color gun. go thorough the convergence routine and see if all the colors are there. If your missing a color, you can purchase just that gun but I would advice that your replace all three. Be aware that this can be costly and in some cases you may have to purchase the whole pc board with the three color guns on it, depends on the model.
One or two of your color guns are failing. On a CRT, there are three color guns, Red, Green, Blue. They work together to produce all colors in the spectrum. If the monitor goes all one color, it generally means at least one color gun is failing. The cost to repair far exceeds the value of the monitor or the price of a new LCD panel.
there are three guns that produce color
red blue yellow they make the spectrum which includes black if one of the guns burn out you loose that color if the gun is good then the color board that controls that color is bad
There may be several causes but, one is that when any color gun is being over driven, the Sony shuts down the gun to protect it. Try this. Remove the front of the set by removing the two screws from each lower corner. Next remove the black panel held on by 5 or 6 screws. Now you should see a panel with 6 potentiometers on it. Turning the ones on the bottom row CCW reduces the drive. Turn the color down and if all the guns stay lit, SLOWLY turn them up until you get the color balance that you like.
I am about to say something that may sound stupid but it sounds like you are experiencing this. After years of use you CRT guns in your case the gun in each one of your CRTs(RGB) begins to oxidize and decrease in its ability to provide electrons for the scaning beam this creates a dark picture.
Common problem? yes, over time, but for it to happen in just six years is strange but it can.
Major Problem to have repaired? No, the technician will use a CRT rejuvenator on all three of your guns and then balance them and you are off and running.
Now the other problem that might be occuring low CRT anode voltage. this could happen.
Common problem? yes, it is the best choice
Major Problem to have repaired? yes and no depending on which components are bad.
