Hello, how are you? I'm telling you that when I tried to repair my Dreamcast, it got even worse. Now it doesn't emit a video or audio signal. I clarify that I know this because I made an audio and video mod that first worked for me. Now the original cable doesn't. I have clarification in case of doubts. Thanks for looking and helping, greetings

Hello, good afternoon. Could it be that my video and sound DAC chips have burned out? Since it doesn't give me a video or audio signal. Thank you.
