Please help me diagnose this issue. I'll spare you all the details of my 6-month run around with the good guys other than to say that one technician told me I had a problem, while the second technician told me that the first guy should have never said that, because I don't have a problem.
I have had two TW40X81s in my house. The first was a store loaner while the second was being delivered. The first had burn-in from being left too long on standard mode, otherwise I would have just kept that one.
Anyhow, those are the backup details, now onto the problem:
I have a hard time getting a good convergence on the SECOND Tv I have. The first seemed to me to be much better, but it could be I'm just smoking funny grass. In particular, the blue gun seems rather out of focus. The first tech opened the TV and tweaked it, but it was (before and after tweak) still at it's best position which isn't all that good. This results in a noticable degradation of quality, typically in scenes where there is white text on the screen, such as during the credits at the end of a movie.
When I move onto the user 9 position convergence, typically I get a blue glow surrounding the cross used to set convergence. This glow obscures the edges of the cross and makes it difficult to converge correctly. In my mind, this glow is also indicitive of a poorly focused blue gun.
I own and have used AVIA to set my picture settings at optimal locations. For fun I have adjusted sharpness and this doesn't seem to change the blue cross in convergence at all.
The first technician felt I had a problem with my blue gun. The second technician thinks that it is really just the difference between a direct view TV and a rear-projection three gun TV, and that I should 'just get used to' the increased fuzziness, 'cause it's a function of the projection method.
Can anyone give me any tips to help me to decide whether I escalate with Good Guys management to get a new TV or just give it up?

It's my experience that most of these 'techs' don't deserve any sort of moniker that would lead someone to believe they have a shred of intelect to back up their title.
"Get used to it" is not what you should do. A properly calibrated RPTV will not have the convergence problems you describe, which is exactly the same thing that happened with my 61" Toshiba. I had an authorized Tosh 'tech' (meaning they were a Toshiba dealer, and were authorized to do repairs...not exactly required to have credentials) do a full convergence on the set which had the same problem...only to have it returned 2 weeks later..with exactly the same problem, but also scratched and covered in dust!
My suggestion is to find an ISF certified tech in your area, and talk to them before setting up an appointment, and make sure they can help you out. I have finally located one nearby, and plan on having my set properly calibrated by someone with the know-how and proper tools to do a full calibration. Yes, it can get expensive, but IMHO shelling out a few hundred dollars to get the full level of quality you deserve is well worth it.
Of course, YMMV.
