No sound perfect image but tsound is no sound | Trail | Splice to the ca15 track that takes audio to the audio and video input audio connectors. This track leaves the ca15 and ends in the positive audio connectors of the audio and video input. It usually breaks near the cv39 on the sima side of the board, just splice it in and that's it. God be praised! | Sinailson furtado |
