The device has but with the default settings some quirks (hence only 4 stars) can be circumvented, fortunately with the correct settings.
If the dynamic backlighting is turned on, the device constantly hum of itself - especially in dark movie scenes. In my unit, it was so loud that it was really disturbing.
With switched Hinte dynamic backlight the hum is gone and it's just a quieter whirring sound.
By adjusting the contrast to 100, also disappears and this one has a whisper LCD finite. (Only when you turn it on quitscht shortly.)
In the image quality had - at least for me - no noticeable influence.
Should not be any digital stations found (in my case initially was missing ZDF, 3Sat, etc.) in service search must be set during automatic station search or the advanced search (in step 3, settings, frequency search). This then takes though more than an hour, but who wants to dispense with ZDF in HD quality? ;-)
On this occasion I was able to support PHLIPS test (support chat and telephone), who directs me to the right place in the Settings menu. -> Fast, good and competent.
For all cable-BW customers: automatic channel update in standby must be switched off in the settings. Otherwise flying during removal and subsequent switching on all digital channels in the favorite list ... what annoys real!
I hope these tips help one or the other buyers and reduce unnecessary returns the device because of an alleged defect.
