Screen only works when phone is open

Hello all. I recently replaced my screen on my 6 plus. Just a week ago it started going black and would take a few minutes for the screen to work again. Now it won't come on. The funny part is when I open the phone up the screen works and as soon as I snap it back into the frame the screen goes black again. What could this be?

I also noticed the cable piece with the brass contacts that touches the metal cover on the digitizer when the corner is pressed against the metal piece the screen dies

My first guess is that a cable on your new display is unreliable: As the cable flexes when you close up your iPhone, one or more conductors in the cable are losing their connection.

If evidence shows that there is an iffy conductor, I'd remove and reattach the display, in hope that it's simply a poorly seated connector.
To determine if it the simple case that the display is simply not displaying anything, I'd try using a USB cable and see if the device shows up in iTunes even with a non-functional display.
If the old working-but-cracked display is still available and viable, I would temporarily re-install it and see if the old screen's behavior is normal.

Looks like bad cable. Would it harm my phone if I keep using it. Should I leave it off until I get it replaced.

It could, it may end up blowing up a backlight filter causing display but no backlight (dim display) ending up in a micro soldering job needing to be done (backlight filter would need to be replaced).

I would replace the display assembly with a new one. I would not use the phone until a new assembly is installed.

i had this on 5s and 6plus, so when open and usable, restore on apple by pressing on button, and home same time until itunes says this phone has a problem….restore it….just as a first attempt at repair

still only works when i opened it up…so pressed on logic board a few times…and in settings , screen lock as NEVER,

screen time off, all other settings off, no fingerprint, no apple ID, only wifi….closed it up and stayed OK

was it me pressing the logic board?…

if all fails can use with screen slightly open I suppose, permanently fixed somehow away from the body?
