55HU7500 strange problem tuning UHD cable

Hi, im trying to tune an UHD channel with the DVB-c tunner. Months ago i tried with sat tunner and all is ok, but now my provider is including UHD channels, and when i do a channel search, or i try manually to tune the transponder the cvhannel is not tuned.

I try with another K series full HD tv in same cable and the channel is tunned but not displaied of course because is Full HD, but not with this H series or another F series.

I think it my be a transponder list issue because other channels that are in same transponder but with other Sr are tunned.

Is any file to modify this transponder files, or add options???
Is there a posibility to add this channel manualy to a chanell list or a file???

Thanks in advance

It's not clear for me whether you can view satellite UHD channels with the receiver's tuner or built-in tv tuner. If you are able to watch them via tv tuner then your problem could be caused by the receiver. It may not be able to decode those channels - even when you can receive the signal.

For example I can watch UHD channels on my laptop through network streaming from my receiver but cannot watch them with receiver - tv combination. TV's screen and tuner support UHD but receiver's chip cannot decode them.

No, the problem os simple.

In ínternal sat tunner, i can tune and watch uhd channels.

In ínternal cable tunner, i can not tune.
Is not a signal problem if i put another samsung tv i can tune channel.

I only can supose that is a search problem with transponder or simbolrate list.

Because if i tune the correct transponder it tune all hd channels that are at 6875sr but uhd Chanel. Is at same transponder ok 6900sr
If i search manually at 6900 it changes automaticali to 6895 and tune hd channels
