I am having issues with my Steam Deck.

After I boot up the screen shows the Steam Deck animated logo, with a loading sign at the bottom. Then after that, the screen turns black - the fan is still on, and there is haptic feedback on the 2 touchpads so I know its on.

Here are the things I tried without success:

• I have tried to fully drain the battery.
• Hold Power button 3 sec
• Hold Power button 10-12 seconds

The only thing that works is if I plug my HMDI cable to the monitor, and the screen does show up now.

What can I do to fix this? In the past, a simple restart solved the issue.

But now my steam deck is literaly unusable because the Black screen appears every time I turn it on, unless I plug it to the monitor, which deafeats the purpose of the Steam Deck.
