I am contemplating purchasing the AVIA DVD for various reasons. Here's the question. Once the T.V. has been setup using the AVIA DVD, is their a need to have an ISF Tech. come out and calibrate?
I understand the AVIA DVD will add time to the life of the set as well as provide a better picture. What would the PQ increase be in a percentage fashion (ie...5% increase in PQ) by having an ISF Tech. come out AFTER I have already completed the AVIA DVD setup.
TV: 32XBR450
I have owned this T.V. for exactly a year today. Will this hinder the AVIA process? I understand that this should have been done sooner.
Thanks In Advance

I think it will depend on how bad the set is to begin with. If it's just a matter of adjusting the standard controls (brightness, picture, sharpness), you should do OK with Avia. If the geometry is out, Avia will only show you this. It doesn't tell you how to adjust it. In this case, An ISF guy would be the way to go.
In general, you should wait one or two hundred hours for your set to break-in before spending the bucks for the ISF guy. Since your set is already a year old, it's all broken-in.

Thanks for the prompt response. I do not notice any GEO problems, although I have not "searched" for them. Not sure if my eyes are weak, although I'm still a youngster (24)  I hear so many people speak of GEO problems it makes me wonder if my set got lucky or I'm blind, ya know?
How common would you say GEO problems are?

A lot of people on this site complain often (flat screens mostly). I personally haven't seen any (mine is a 27" WEGA). I think the largest tubes are more likely to have the problem.

At least on my 27" flat screen the geo problems are only visible when I use a test DVD like Avia...watching regular TV I don't notice anything.
As had been said previously, fixing color balance and the like is easily done with the AVIA dvd, but as far as geo problems I'd definately have a tech do it instead of myself.

Avia will get you a good picture on your own. An ISF tech (good one) will get the best possible picture out of your set and is always needed. Wether you feel it's worth the money is a whole new issue. An ISF tech's main adjustment is grey scale which can only be done correctly and accurately with very expensive instruments ($10,000 ones).

Ok...thanks everybody for the responses. One last thing regarding the ISF Tech. You state they will get the best possible picture out of the set, but realistically is this anything more then a 1% - 5% increase in noticeable PQ?

Depends on how bad your set is to start with and how well you do the avia calibration. An estimate would be:
Full ISF from out of the box settings: 100-200% better (this is subjective of course because the amount of difference to me could be totally different than the amount of difference to you).
Full ISF from propperly Avia calibrated set: 50-100% better.
Again, this all depends on how close your set is to proper calibration right now. If the grey scale is very close to D6500K already for some miraculous reason, you won't notice much difference at all besides the convergence and geometry and user settings.
I have never heard of this though, of all the ISF calibrations I have heard about from various customers of techs the grey scale is usually very far off track.
My suggestion is spend the extra $300 and be absolutely sure you have the best pic you can possibly get.
And make sure you get a good ISF tech too. Don't get ripped off!

Ok...and thank you. I'm in Denver as you noticed over there <<<. Any reccomendations in regards to finding a good ISF Tech.? If not, any rule of thumb to follow and abide by? Thanks again.

Visit the Home theater forums like
Hometheaterforum, AVSforum, and Hometheaterspot.
Do a search for ISF and Denver or ISF and CO. You may find something.
Also, check to see if Gregg Loewen will be travelling through anytime soon. Here is his website:
Lion AV
Also, check the ISF website:
ISF Site
Type in your area. Be aware that just because they are on the ISF site they may not be recommended techs, that just means they have been trained. Once you find out who they are you can do another search for credibility on the home theater sites.
