Hi All, was hoping to get some direction after a long struggle with getting the sound working on my LC I have run out of ideas? So far the following has been done:
1. full recap of board and TDK PSU (psu had a broken R51 resistor on top of leaking caps) but is working now
2. checked all traces /via's from sound chip all good
3. Speaker tested working but also tried another speaker still nothing
4. headphone jack no sound
5. pram battery new
6. Board is very clean, no corrosion
What I have noticed is that the speaker will make static noise when hdd, sdhdd or even floppy drive are operating?
Anyone have any suggestions I can try?
Thanks in advance
