DANIEL: Thank you for purchasing the Samsung TU7000 and for your review. I am very sorry you are viewing scenes that appear too dark. A new firmware update has been released to address this issue. You may also need to manually reboot your TV after the update by either unplugging the AC cord or by pressing and holding the power button on the remote until the TV powers off and back on. Using your TV's remote, navigate to Settings, and select Support. Select Software Update, and then select Update Now. New updates will be downloaded and installed on your TV. Updates usually take a few minutes; please do not turn off the TV until the update is complete. When the update is finished, the TV will restart automatically. If there aren't any new updates, select OK to exit. You may want to enable automatic updates for convenience. Select Settings > Support > Software Update, then select Auto Update. If you would like to update your software using USB, please check for the latest version on the Samsung website.
