Ps4 doesn't start anymore who can

I have 2 TVs. A SmartT. Von Grundig (800 euro) and a Medion (40 euro) both have HDMI connections. I no longer wanted to play Ps4 on the large Grundig television and then wanted to connect the Ps4 to the old Medion television accordingly. From this it has been concluded that the television shows no picture. Then I started blind on the Medion TV without seeing anything (thanks to YT tutorials I was able to orient myself) and started the Ps4 to change resolution with 480p. Didn't work either. AFTER I connected the Ps4 to the Grundig again and before that everything just went num I have no picture. When I go into safe mode I don't see it either, I just hear that the Ps4 comes on but jz doesn't show anything on either of them. Hope for quick help…

How do I start the PS4 in security mode?

Turn off the PS4 system by pressing the power button on the front. The power indicator light flashes for a few moments and then goes out.
Press the power button again and hold it down as soon as the PS4 system is switched off. Release the button when you hear two beeps: one when you press it and the other seven seconds later.
Connect the DUALSHOCK 4 controller using the USB cable and press the PS button on the controller.

Already tried it.

I think the HDMI on the old device connection is not compatible

But why is it suddenly no longer possible with the new television… Before that it always worked.

You hszzesz switched the box to get a picture of the old one

ph

Yes I have and that's why I don't get a picture of the new one.

Ky

Can't that go backwards?
