I have perhaps some stupid questions about camera black level.
Does this apply to all models using the chdk?
Is it for using the conversion to DNG in camera or does the DNG4PS2 program work with this change?
I use the DNG4PS2 because converting to dng in camera took to much time but I'm not always pleased with how the DNG-files comes out.
I have a PS S5IS firmware 1.01B

No, it doesn't. Black level is set to 31 per default. But each camera might use an other value for it. S5is uses 31. Have a look at camera.h....

As far as I've understood Black Level is used as a threshold in RAW pictures and also will be written as descriptive value in DNG-file. It's definitly not a clear answer to your question but I don't know how DNG4PS works.

I've tried
- to turn off Canon menu - Power saving - Auto turn off
- to turn on Canon welcome screen
- to turn on CHDK welcome screen
all sounds were always disabled

next:
- I'll try to format SD card again (A-Data SDHC 4 Gb, Class 6)
- or try to turn ON chdk welcome sounds :]

I see black screen too but the screen turns off when I release the button (play, or on/off). (I can hold for minutes.)

Strange.
Are you using the latest CHDK version from autobuild?

Blue led means CHDK is starting up.
What happens if you are using regular Canon startup? Did you encounter similar problems?

First of all, I'm using firmware update method as default startup method. Camera will be started in normal Canon mode and I can decide if I'm using Canon or CHDK mode. I have some trouble with battery power but not generally with startup.

Yes, it's definitly independent from startup method. But I would give a hint to zodiac757 how to narrow down the problem. I think, fw update method could help, because Canon mode startup and CHDK startup will execute one after one. If the camera "dies" already in Canon mode, so it might be a hardware problem (and I think it is one but only if zodic757 uses the latest CHDK version).
