TV Model: 47PFL7008
Previous Firmware: 171.51

+ colors are great
+ no flickering

- menu and switching channels is way too slow
- and even slower during DLNA playback
- 1-2 times per week TV just shut's down the screen
- when using HDMI ARC there is unexpected behavior like playing from both speakers and tv (echo), shutting down when Skype launched, not playing at all
- when connecting USB HDD and flash drive together - TV will say "found usb device" and will show me flash drive - this happens 3-5 minutes after tv is turned on and will stop anything you've started watching without ability to get back easily.
