My set produces some very non-linear saturation sweeps. Green, cyan, and magenta are the worst offenders. I'll post up an image when I can get to the computer they're on.


If anyone's aware of how to eliminate or minimize this, I'm all ears (or eyes, rather).

no i've not measured saturation sweeps. is that on a standard test disc, or are you using one of the specialty ones?

I'm using the built in pattern generator in HCFR but the AVSHD709 disk has them for 0, 25, 50, and 100%. The advantage of the built in generator is that you can set 8 or 10 points along each axis and get a good image of saturation tracking.

Here are a couple of examples showing the issue with saturation tracking. The first image illustrates the non-linear sat-tracking when a calibration based on accurate primary/secondary points. Clearly, the pri/sec points are not particularly accurate, but the result would be much the same if they were dialed in. I've marked the Color Check points and their respective targets to show how far off these points are due to the tracking issue.


The second image is my best attempt, thus far, to calibrate based on lowest average dE on Color Check patterns. As is evident, green, cyan, and magenta are the worst offenders. Magenta is manageable, green causes some undesirable errors, but cyan results in huge errors.


I would like to see the results of what others have achieved in terms of saturation tracking and color check accuracy. If anyone has any tips on how to correct this, I'd very much appreciate it.


This cal was done with standard gamut...my next step is to use expanded gamut.

For comparison, here are a couple of caps from 2 different Vizio models. While these have much better spatial (x-y) tracking, the distribution still lacks linearity. In my limited experience, spatial tracking errors are much more difficult to compensate for compared to distribution errors.

Error Codes

My beloved 3 yr old lc60c847ou shut off today and will not turn back on... I am getting one fast and 3 long blinks on the front power light....any ideas on what the codes might be? I am thinking power supply (which don't seem to be readily available) or possibly main board. I have tried all the reset tricks I know as far as holding the certain buttons down while powering up with no success. Thanks.
