my screen is not turning on but my sound is working

My switch screen itself isn’t turning on, but when I turn it on I can hear it. My joy-cons still connect to the switch. I have replaced the screen once and it worked for a couple of months. Anyone got a solution?

How did you replace that screen?

I looked up a YouTube video and followed each and every step

If you have that much ability already then I suggest try to re-insert the ribbon cable

Biggest suspect is simple a botched job or defective replacement part

You can attempt to do it again if you want, with new part
