DM 800 bug - brigtness and contrast of OLED display cannot be changed

  • I am using DM800 with E2 image release-dm800_20081025.nfi. I tried to change the OLED display contrast and brigthness but without any effect. For example i set up config.lcd.bright=0 and config.lcd.contrast=0 but display shines on 100% without any change. Image release-dm800_20080912.nfi has the same bug. Any suggestion or plan to correct this bug?
