Philips 49PUS7181 / 12: No Image with HDMI Connection to Digital Polsat HD Receiver

Hello,

For several days, there is no vision when connecting an HDMI TV - HD receiver of digital polsat. No picture . However, the SCART - SCART connection works.

It is puzzling that with HDMI connection there is a menu available (from the CP tuner), i.e. you can display the menu, configure the settings, but no picture. He managed to start the sound via HDMI, the subtitles are also displayed (translation for example to tvp in Polish), but still without a picture.
I came up with the idea (because I thought it was the fault of the cp tuner) and lifted another CP tuner in advance (I have two receivers in one house), unfortunately the situation is the same.

I connected my laptop to the HDMI - hdmi tv and everything is fine here, the image is displayed.

Does anyone have any idea what might be? I tried various methods in configuring resolution changes on tv and tuners, but to no avail.

thank you in advance for your help.

Change the HDMI cable.

I come back to the matter.
After connecting to a completely different set-top box (at a friend's), the following message appeared on the TV:

How to solve it?
in addition to the service.

I can't because I bought this one in December and spent about 4,000 PLN on it
