I sent the link to my son in Arizona. He just bought the Hitachi 57TWX20B and the Panasonic DVD-RP82. He's loving it. Thanks for posting it.

For anyone interested in a ISF style calibration or greyscale in Western MA, or even New England...

I would highly recomend BobL and his partner Rich.

They are great guys, and competent calibrators. Both have been "into" audio and video for years.

Bob calibrated my Hitachi SWX shortly after he completed the ISF course and although it was his first Hitachi, his knowledge and experience showed and he and his partner Rich did and excellent job. Since then they have calibrated all sorts of displays, including mine again.

For anyone interested in a calibration in the area, I highly recomend him.
They have all the equiptment needed for a great calibration

You can hit him here at AVS:

You can hit him from the Imagescience website.

Is there a recommendation for someone to do calibration of rptv and/or front projection in Florida?

Here's a nice review by one of the "Spots" editors getting his Set ISF'd. He gets the full treatment. (wonder what that cost!)

Most Calibrations run $250-500.

You can pay more if you have more done.

Things like focus and geometry and lestripping are somtimes considered extra by some, yet included by others.

Particuarly Geometry can take a very long time if it's way out of wack, Time is always money.

To have a grayscale set.. and that's it,.. should go about $300 or under.

I think I'm going to take the plunge when my set gets fixed and I move. $600 is gonna hurt but I think it'll be worth it in the long run. *crosses fingers*

Well I emailed Gregg Loewen:

$50 travel then $400 for a setup and DVD gray scale
$150 for HD work
$150 if you want Duvetyne lining

Now I'm looking at $450 for setup and travel and $150 for HD work = $600. I think I'm gonna skip the Duvetyne lining (can't afford it) and I hear mixed results (some see benefits, some don't).

Greetings

Don't be too eager to jump at HD calibration. Take a look at it after the DVD part is done. The HD in most cases will already be "close enough" as a result of the DVD being done.

Aside from that ... Doing HD grayscale is more of a waste of $$ since you are doing it to match the signal content which is irratic like cable or satellite. If you are not doing it for those sources ... why do it for HD?

It's usually an extra you can do without. However ... if you want it checked out ... just pulling out the equipment will cost you that $150.

Thanks again Mike. That makes sense. I think I'm going save myself another $150. Although she doesn't know it my fiance' would thank you. ;)

$450 is a lot more reasonable but $300 would be better. :D

Hi guys!!

For some the $150 is not worth it, for others it is.

The $150 for HD includes gray scale work as required (many HD sections go purple towards the dark end of the scale), color decoder work as available (sony and Hit), front panel control set up (within the service menu, as with Toshibas), and any geometry , overscan and convergence work (Hits and Toshs dont have this).

Regards

Then the extra HD work is probably worth it....

I would spend the extra to calibrate the HD 1080i section if you watch alot of HDTV...

Thank you for the links and info Mfusick. Sometimes hanging out in these forums we assume a certain level of awareness in the participants of such basic issues, but there are always newbies who appreciate the information.
(And I appreciate learning more too).

There is a base cost just to get to the clients home and get all setup. I would recommend getting the HD calibrated if it needs it. As an example, it's $150 when the calibrator is there with all the stuff ready to go but easily $300 after the fact to have him come back. This is also why some of us charge for some extras and others don't - we are already there or working in that area anyway.

Yes.. I know alot of people see this "ISF" in so many posts and have no clue what it really means...

Good to teach others...

I learn alot myself too..

I've been here a while now... and I think I know a whole helluva lot about RPTV's....but- I still learn somthing new almost everytime I visist.

Just had my Sony 51HW40 ISF'd and it was worth every penny. The education I received about what a properly calibrated display should look like was itself worth it. I frankly did not believe my set was capable of displaying such a wonderful image.

IMO, unless you are a very, very accomplished tweaker, you will not approach what a good ISF tech can do. These guys earn their keep.

I also had a good experience in the Denver area when Bill Gambrel (GambrelW on these forums) came out to calibrate my Hitachi 57XWX20B. He took his time and really paid attention to the details on issues like geometry, convergence and grayscale. The cost was reasonable and I was able to ask alot of questions during the procedure. He even drug his equipment downstairs and cleaned up the grayscal one an LCD front projector for a little extra money.

When it was all done the picture on DVD and HDTV looked great. (Unfortunately, the garbage in - garbage out still applies with basic cable reception.) Given the high cost of the TV itself (as well as other peripherals such as cables, surge supressors, etc.), getting a quality calibration only makes good financial sense.

Bill really knows his stuff and really knows Hitachi....

He's probably one of the only "Hitachi calibrators" out there.

Hitachi is his bread and butter and he owns one....owning one makes all the difference in the world because the quest for perfection does not end when it's your own Set.

Anyone ever have a warranty claim rejected because they found out the set was calibrated by an outside technician?

I was able to locate local ISFs on teh ISF web site.

I am interested to hear reviews/recommendations of ISFers in my area.

Is there a forum on here elsewhere that has this?

I am looking for reviews/recommendations of ISFers in the Columbus, OH area. :>

Thanks,

Greg,

Are thorough calibrations always done through the service menu?? I have a Hit 50vs810 and would like the display to look the best it can.. The service menu has an adjustment for 480p amplitude... It is an auto adjustment.... Service manual says to input 525p(480p) of RGB amplitude adj. signal into INPUT 1 (Component) input..... What is this signal? And what does it look like displayed.....? Thanks.....
