Hello guys. I'm having some issues to have the speech working on my flight 2000, so I hope you can help me. I have read all related topics, and tried everything.

I got my flight 2000 without the speech card, so I bought it from a pinside member, that had tested it ok on his flight 2000, before ship it to me. The issue is that it speaks at the right times, but only garbitch.

I have already checked the jumper on the SB-300 and it's ok. Since the speech happens, also proves that is getting out of the VSU-100 and amplified on the SB-300.
I have changed all caps on the speech board.
I have checked the eprom. I have read it and compared with the one at IPDB, and it matches perfectly.
I have checked the cable that goes from the VSU-100 to the driver board, and all wires are ok. Besides, all lamps work just fine, so it should be ok.
Since the speech sounds happen on the right times, I believe that the main chip on the VSU-100 is ok.
Any input will be highly appreciated!

Hello. Thanks for the feedback. It's like clipping. I'll make a short video and place the. Link here.

Hi. Here is the youtube link with the speech sounds.

Thanks!

Hi. I just checked the 5v and the -10v. All good.

Great, thanks for the tip. I'll reflow solder as the first step. If the issue is still there, I'll try the headphone with dc blocking capacitor. I've never heard about this method, but I'll do some research on it, since I don't have a scope... Last case, I'll replace all the components on the audio output path.
