Evening everyone. I just recently purchased a capture card for the original DS. I installed the card without any issue and it was working for the first 20 minutes, but then it broke and I haven't been able to fix it. I have E-mailed 3Dcapture about the issue and messaged the admin here, but they are not responding. I spent $70 on this and another $50 on a DS to take apart to install it. It's not cool that I can't get any kind of response on how I can fix this.

Have you checked the forum? Perhaps your question has already been answered in another thread.

Yeah I checked and googled it, but I couldn't find any issues similar to mine. Also I'm actually an IT so I really went all in on trying to fix this myself including taking apart the top half of the DS and reseating the screen cable. I'm literally up against the wall here with what's left that I can do.

If the cables aren't straight and completely pushed in, it won't work. If connectors are chipped / broken, it won't work.
You can use the white line on the DS mainboard as a guide, it should line up with the stiffener part of the cable.
