My ps5 stopped working and I really need help.

For context: it belongs to my brothers, but we all agree to share it. I don't know anything about these consoles since I've played Nintendo all my life, but last night I wanted to try playing for the first time.

I pressed the power button on the console bc I assumed that's how you turn it on, but apparently it was already on and connected to our Samsung TV, just in 'sleep mode.' It didn't 'turn on' and the lights on the console never flashed, so I repeatedly kept pressing the power button in different ways but nothing worked. After doing this, our TV somehow stopped recognizing the HDMI cable that connects the two and it changed from showing the ps5 app icon to what you see in the picture.

We tried unplugging and plugging the HDMI cable a million times but that didn't work. We tried other HDMI cables but that didn't work. We tried tuning our tv on and off but that didn't work. We tried pressing the power button on the console repeatedly and holding it down but that didn't work. I tried looking at different videos and posts online. I tried contacting Playstation support and the expert told me that it sounds like a potential hardware issue and I should send it in for repairs but I'm not sure, and I'm worried this could be extremely expensive. Our console is over a year old so it probably doesn't have a warranty anymore and I'm getting desperate and blamed for "breaking" it :(
