My $39 ebay 100% Working Defender Sound Board didn't work when I plugged it in today... I'm asking the seller to refund me $20 for a broken Sound Board, but it'll cost me more than that to fix it.
I was going through the Williams Recap Sound & Speech pdf to diagnose my board and I changed the 6802 cpu and sound rom from my good working sound board to the bad sound board but it still didn't give sound. Now the pdf says touch jumper W-15 but that jumper is not listed anywhere in the Drawing Set pdf. So how do I check my audio amplifier circuit if it's good / bad before I go to diagnose the IC's if they're bad.
- I fixed my bad Stargate Sound Board by diagnosing a bad Sound ROM; I exchanged the Rom on my good board to the bad board and then it worked fine. So I ordered a sound rom from hobbyroms.com.
