my xbox doesn’t show any display or shows it for 10-20 seconds before turning off then turning back on again and due to that happening it’s made my hp v28 4k monitor (if I’m right) stop working for everything I have opened up the xbox to see if it’s anything with a connection to the hdmi but a cable that’s like a ribbon cable that has two screws into it was missing part that’s soldered (I have made keyboards so I’m hoping it’s the same situation) is off and slightly damaged i don’t know what that cable does and if that’s what has caused the issue I have tried multiple different hdmi cables power cables and what not and it still doesn’t work any help to know if it is genuinely broken would be appreciated.
