And I think it's fixed... Tried reseating ROM... Pulled sound input connector and grounded each pin to see if I got sound. Thought I faintly heard something like when pressed diagnostics button. Could it really be the speaker? Luckily I am a hoarder and saved my old firepower speaker! Just hooked up and boom! Works! Can adjust volume and everything! Of course I notice there was scanbe socket on sound rom so that will have to go in the future! It is never the speaker but this time it is! I was ready to replace 4050 buffer because it's always the 4050 buffer but wouldn't you know it was actually something simple!!!! Fingers crossed this was the problem!!!!
