My Panny 47X54 has an unusual green gradient tint on the left side of the screen, one that mainly affects whites and blues. I have heard that it is due to magnetic interference -- I eliminated the interference, but after looking through similar cases, I've found I probably need to degauss the screen manually, as the auto-degauss that the TV does when it turns on does nothing to alleviate the problem.

So my question: can it be done, and how?

not sure, but have you unplugged your set and give a few and replug it back in and see if tht works??

Yes I have... it showed no improvement.

This is unlikely to be of help. The kinds of interference issues that cause color abnormalities on direct-views do not really impact RPTVs. I would not expect degaussing to have any effect on the image except perhaps some impact on convergence or beam focus if indeed it is true that your set got a bit magnetized.

What is there to do to get rid of a color abnormality? I've looked into convergence, but it's fine.

Anyone know what I can do to get rid of this?

Chris was right about degaussing being more of an issue with direct view CRTs - BUT I have seen issues where large speakers were placed next to CRT RPTVs. Is that a potential problem here?

Also, is this new? (If so, what changed?). Or are you for some reason noticing something that may have been there all along. If it has been there all along, I would suspect that it is a normal condition that can be eliminated by a calibrator using a process called "lens striping".

Yes, my CRT RPTV was once affected by large speakers being too close.

The magnetic effect of speakers or other fields will almost always cause a differential convergence shift in the three crts. RPTVs almost never need to be degaussed. I have seen starnge focus issues that can be caused by a bad CRT or modulation circuit that can cause something similar. Try putting a full field of each color on the screen and see what each looks like and put a dot field up on each color and see what the focus looks like, as well as the shape of the dots.

I'm pretty sure this is a recent problem -- I had a professional calibration, and it was fine until just a couple weeks ago. He did lens striping... is there any possibility that I could do a lens striping myself? If so, how would I go about doing this?

I suggested in the other thread that it was possible something like the striping came loose. I again suggest you look into service or talk to the calibrator. What you describe as a fast onset of colorshifting is very strange and does not make sense to me, i.e. I cannot explain why that would occur for any common reason. Speakers/magnetic fields nearby shouldn't affect light output in this way in terms of discoloration (for an RPTV, it will for a direct view), but may affect convergence. You previously described that convergence was fine. I don't know what could cause this other than problems in the display. If there's some kind of zone-contrast modulation board going bad or something, I've heard of that happen on CRT FPs, but even that is unlikely to happen on an RPTV which is unlikely to have this kind of board in it. I vote for taking the set to be looked at by a technician, because what you are describing does not make sense.

Now, say it's just, for some odd reason, burn-in. I've read (through the burn-in topic on here) that you can steadily display another color to get rid of the burn. Is there any specific color I would have to use to negate green?

I think Chris hit it! It sure sounds like the striping came loose. Striping is usually tape over the edges of the CRT lenses to "shade" one side of the image. His advice to call the calibrator is probably the best course. If he is local (and this is one reason to hire local calibrators if possible), he may be willing to return at no charge (I know that I would). If he is not local, and you are willing, he may be willing to talk you through doing it yourself.
