42PFL7606K/02 Automatic channel installation doesn't work, manual does

[kiwi_99]

If I enter a frequency (e.g. 306 Mhz) manually, the tuner finds channels and I can store and use them. The infos on the screen are e.g. Signal quality 94 (BER:0.18x1E-6)
signal strength 93.
QAM modulation 64-
QAM Symbol rate 6.875. (see attachment)

So if I have a lot of time I can look at the frequency on my Kathrein tuner (see attachment), enter it manually on the Philips, let it search, it always finds channels on that frequency, then I can store the results.
It should work automatically, but the automatic channel search with same start parameters (country germany, Cable connection) returns 0 digital channels.
