My top screen goes darker at certain angles and I am wondering if this is because the top LCD is dying or because there is a ribbon cable not seated correctly.

Is my touchscreen acting like this because I did something wrong replacing the touchscreen, or just because the touchscreen replacement is faulty? Everything else about the touch screen works just fine, it’s just that part on the left and a little bit on the top part of the touchscreen

What happens if this solder is damaged?

I meant damaged my SD board

Hello everyone, so I tried to fix my 3DS top screen bit before I did that I replaced my touch screen and the buttons. While replacing the buttons and touch screen I may have damaged the top screen ribbon button, but that’s okay because it’s the old one. But I may also have damaged the SD Board because it does turn on but it doesn’t show the normal Text, what do you guys think happened to cause this?
