No video on any HDMI Philips 4k TV


Novice Member
On a one-year-old Philips 4k TV, suddenly all HDMI channel inputs reproduce no picture, just audio The sources are a satellite TV box and an Android media player. Both these inputs work fine with an older TV monitor. All internal video display---menus, adverts, all the trash that comes with this TV---works fine.

I've unplugged & reset everything connected. No joy.

No recent electrical storms or power issues here.

A one-year-old TV monitor ought not to fail. Is there a known issue that corresponds to this pattern and that can be fixed, or do I just need to mark this TV toast and find a better brand?
