Welcome to the Community,
Regarding the Issue you can first try installing the Yoga Control Mode from https://pcsupport.lenovo.com/ just enter your serial number so it can find the right version and select manual update after clicking drivers as shown below.
Hope this helps and let us know how it goes,

If the laptop was in sleep mode, the keyboard would not be lit up and the power light would be flashing so it's unlikely to be in sleep mode. You could have a faulty EDP cable that runs from the motherboard to the LCD. If that's the case, I wouldn't keep bending it that far.
Maybe test it by playing some music and bend the screen back until it goes black. If it's a cable problem, you should still hear music. If the computer is turning off or going to sleep, the music will stop.
