Hi everyone, it's been a while since I've messed with this set but I got the itch again and I need some help. Thanks for your help.
First the background:
TV is a Hitachi 65T500, only tweaked with user level controls so far.
DVD player is a Pioneer using component output.
Dish Network HD DVD box using component.
Wii, Xbox, etc...
There is a switch box between all the components and the TV so that the TV only gets fed with component cables on input 1, and all the audio and video switching is handled externally.
This is an HDTV compatible device and I didn't notice any color changes when I put this in line.
I just put command cloth in the TV this last week to help the blacks out a bit and I spent several hours last night toying with a program called HCFR and the SpyderII sensor. I was using the DVD, it is in a PAL format if that matters, which the creator of the software provided and I started adjusting. I was concerned though that when I compared the colors from this DVD to my DVE disc things looked different.
Before I changed anything I reset all the user settings to 50 and put temp on standard, I also set the color system to AUTO instead of specifically SDTV or HDTV. I then setup the sensor and the SW and ran the test on the DVD and looked at the results. After the initial measurement and documenting I began changing user and ISF settings.
I set contrast to 28 and brightness to 48 to get the Gamma as close to 2.2 as possible, I then had a K reading which went from 3000 to 9500 along the 00 to 100 IRE windows. I also measured primaries and secondaries, this showed that red and blue were close but green was way off to the NE of the standard dot on CIE, the secondaries were severely off as cyan and magenta were too blue and yellow too red.
Now I went into the ISF menu and started adjusting drives and cuts only on the -S setting, I have the service manual and documented everything I changed so I can put it back. Using the 90 and 30 ire windows I tweaked the blue cut down a little to make it fall in line at 90 and pushed red and green up a bit. Then at 30 I pushed red and green down a little bit so that I ended up a close to 6500 as possible. Is this the right way to go about this or should I reset it all and start over?
the measurements afterwards showed minimal change in gamma, a grayscale from 5000 at 00 to 40 and 6700 at 50 to 100. The CIE chart still was off on green by a bit, red and blue were off but closer. The Cyan was very close, yellow and magenta were still off. I then tweaked the color settings in the user menu and got magenta a little closer.
What steps did I miss and should I have even touched the cuts and gains? I didn't venture to the pots so don't worry about that, I'm no where near that brave yet.
Here's the summary of my steps:
Set gamma, using user brightness and contrast.
measured gray, primary and secondary.
adjusted gray, using cuts and drives.
re-measured gray, primary and secondary. Still OFF
what did I miss?
