I tried to activate the ISF modes on my 500m and my TV bricked...
Haha, just kidding!
I actually did activate the modes, and it worked like a charm. There were several times where the "Start ISF" didn't actually work (something about "Input string error" and stopping the load). Anyway, I felt I "messed" up a couple of times, but nothing serious happened.
The ISF-Day mode is amazing! It's well worth it to activate it. I think the KuroControl program is great. If you plan to use it, take it slow; if you do it too fast, stuff doesn't load all the way. I would do 1 input at a time, then exit and close the program, then manually switch the input with the remote, then do another input. Also, always remember to exit ISF before closing the program. Otherwise, I don't think anyone could mess up so badly that it would harm their TV, but then again, you use the program at your own risk.
Also, I have a question. When checking my Picture Settings, I see that Gamma is "3" and grayed out even though I manually set the color temperature. Is this correct?
Here's a picture of the ISF-Night:
***IMPORTANT CORRECTION: In the picture, my ISF gamma numbers are 9 and 10. This is INCORRECT! Please use 4 for -1 and 3 for -2!!! ***
