Just bought a new Panasonic 40" Viera TH-40D4000Z:

Problem is, the greens are too prevalent, especially the lighter shades. I even see a greenish cast in some surfaces that shouldn't have one. That said, the whites are white and the other colours are pretty good.

 

I've done a factory reset and wound the colour down to the lowest acceptable level, but the problem, although moderated, is still obvious. The TV is definitely in HOME display mode.

 

This set has no individual colour component adjustment, just global colour. And it's regardless of input source: TV, disc or USB media files all exhibit the issue.

 

I'm sure you'll appreciate this is not a matter of taste. It's a definite aberration that once you become aware of it is very unsatisfactory. Software version is: ver.1.040. Bought from Noel Leeming.

 

Has anyone else noticed a similar characteristic in Panasonic sets?

 

How good are Noel Leeming/Panasonic's return policies?

 

Side note: I'm not too impressed with the viewing angle on this set, but that's probably unrelated and isn't a deal breaker.

Sad to say, you pay your money, you get what you paid for.
Colour accuracy in basic TV's is just one of the many shortcomings.

That seems more like a glib passing remark than an answer to my questions.

 

I could have gone cheap and bought a Warehouse Veon for $450 or similar but I decided to go with something better at $689. If I've wasted $239 dollars, that's another story but I certainly expect better from Panasonic than an in-house brand of dubious provenance.

Panasonics have a typical look that layers green slightly dominant, especially in driven modes.

Try Cinema or True Cinema and normal or warm colour setting.

Other than that someone like myself can tweak settings in the service menus to improve the white balance.

Thanks for that.

 

Can I access the service menus?

 

Should Panasonic support know about this, and would they admit it? Are you suggesting that all Panasonics exhibit this tendency?

 

I've sampled the cinema modes but they tend to be a little too muted if that makes sense.

No don't go in to the service menu without knowledge of what to touch.
Doing so yourself will void the warranty, if still under warranty.

Also I have $25000 worth of measurement tools so I can accurately adjust the parameters, you need some of these at minimum to adjust the white balance. You generally can't do it by eye.

As far as Panasonics go, well every brand has always had a "look" to them to stand out on the show room floor. You don't see the slight green dominance under typical show room floor lighting.
It is only slight, more obvious with some settings combined with your home lighting and wall colours.
