JVC HM700... noise only on old cameras?

A friend of mine bought an HM700 like mine. Mine is one of the first ones (so old I couldn't upgrade the firmware) and his is quite new. We put them side by side. All settings to 0. DNR off. Everything the same (lenses, etc..). Result:
Mine has less blacks, less colour and more noise and a slight "greener" white balance.
I remember in the first weeks, I told the reseller, the assistance and even on this same forum about the noise and everybody told me that is normal with JVC PRO series, GY 200 was the same .. etc..
What should I think now? Anybody was able to notice some differences?

Like you, I have one of the first HM700's on the street. Mine came with the Fujinon lens because the Canon lens that was supposed to come with it wasn't ready yet. However, I've been able to upgrade mine without a problem. Twice now. I've not heard of any HM700 not being upgradable. I would suggest you're going wrong somewhere and need to review and understand the upgrade proceedure.

I've posted a couple of examples of my work here that was shot with my HM700 and the results are terrific.

I got it with Fujinon 16x (not 17x) because JVC Italy had no Fujinon17x and ws selling it like that all in bundle with Sxs. I did the first upgrade (SDHC clas10) but I can't do the 2nd (MP4 without SxS and DNR improved). JVC confirmes I can't and that it has to be sent to them. In any case my side by side test was with 2 cameras same lenses and DNR off so this should not be an upgrade problem but an "old CCD" or similar problem

If you can't update the firmware yourself then you will have to contact your local JVC service facility.
All of the cameras should be able to have their firmware updated, but it is possible that different revisions will require some other form of servicing to accomplish it.

I will.. but the guy already said on the phone that he can't do much.. There is no firmware upgrade for mine.. so either he has to change the chip (difficult!) or I have to stay with what I have

When I got mine I noticed a bit of noise,even without any gain added, but after following the advice here:

http://www.dvinfo.net/forum/jvc-gy-h...-gy-hm700.html

The noise factor went down quite nicely. ( I try to stay away from the gain switch, or no more then -9 cause it does start looking nasty very quickly )

I also have one of the first ( And I usually wait 6 months for new stuff!...but I didn't want to deal with tape at all..and Panasonic's cards are way too much! ) soooo.

Mine is also wanting me to send it in to JVC...cheee! I am waiting for a call back from my cam dealer shop to see if they can possibly do it there..we'll see..

All in all, I like this cam,

I f you refer to this advice...

Detail NORMAL
Master black -1
Black Toe STRETCH, Lev 3
Knee MANUAL 80%
DNR OFF

Still I don't understand why with same settings the older one is worse
