Sorry to keep asking question. My projector having the problem so i need to support from everyone.
i have a problem with color is more red at projector DP2K-10s:
The first, i select the pattern white color ( you see the photo 1), the image is not good.
And then i change pattern (photo 2), the image not good also but 1 second later the image become good better (photo 3).(That is very strange ??????? )
After that i select the pattern white color again. (photo 4), the image is ok. (you can comparison (photo 1 and 4) to see differently ).
And finally i show the movie but the image is not good again.

i hope everyone give me the idea good better.

The macro for flat and or scope may have the wrong PCF file, or the wrong MCGD file. Either one could effect the color. Selecting the test pattern should select the correct one, but it could be a glitch in the system, which is why it looks good after the second test pattern corrects it. Check that both Flat and Scope have the color issue, and also if one does and the other doesn't, try going back to the bad one after the good one. Does the problem go away?

Thanks for your comments. I select DCDM_XYZ_185 for Flat and DCDM_XYZ_239 for Scope, that is correct right? Maybe you thought the MCGD is wrong (measured color isn't correct) so I selected the basic file. The current is bad also, althought I remove the ICP and reinsert back icp board again.
And projector 10s having other problem with dowser. When I push OFF button of dowser, i can see the light on lens
Who does used the Barco 10S and met the problem same me?

Unlike its larger brethren, the 10S doesn't have a physical shutter - the dowser button/command only blanks the picture, which means you always get some light on the screen. Ie. dark grey instead of black.

First check the dark test pattan,if you have any other color in this test pattern, DMD chip or interface may malfunction.
If the normal,it may be back single plane or icp board failure.

Strange. I suspect the ICP or light engine has a problem. If you go into diagnostics/tests in the touchscreen you can also do test patterns: if these are OK, possibly the Barco controller system is acting up and telling the ICP to do weird things when you select a test pattern from the main menu?
You can even try the TI "ICP and Enigma control program" and put up test patterns from there, that talks directly to the ICP and skips and of the Barco software.
When you select a test pattern it uses a special "test pattern" MCGD - so your "measuredcolors" MCGD isn't the problem.
I can't guess how color could be OK for a few seconds then change back to the pinkness.
What do you mean by "the current is bad also"? There is some weirdness with CLO in the 10s (it seems to measure output light rather than input light - the LSC sensor reading changes with pattern or image brightness). Barco says the fix is to install the SCC file as described in InfoT 1086 - this seems to say only do it for a replacement light engine but the word is that it has to be done (get the light engine serial number then download and install the SCC file for that serial) for new 10s projectors.

Hi Dave,

You can display test patterns from the ICP or the HDSDI boards under DIAGNOSTICS-TESTS-VIDEO PATH.

Those are indeed quite useful, they helped me once to diagnose a bad HDSDI board (patterns were ok from ICP, bad from HDSDI).

If I was told correctly, the patterns under TEST PATTERNS (at least the RGB ones) are generated by the formatters themselves.

Thanks for your valuable inputs and I also have constantly received a lot of input from Barco.I am therefore convinced that Barco 10Sx is also like any other models that are easy to install, easy to use and easy to troubleshoot.
