Hello All,
Hoping to get some help with the internal speaker not working. I was testing a logic board that I recently bought as an extra to have on hand. So I swapped it into my color classic and bent a pin on the chassis connector due to a bent pin on the logic board. Long story short, I had to dissemble the Mac to get that pin back into shape.
Once reassembled, I turned the Color Classic on, the speaker let out an awful long drawn out whine (kind of like an LC that hasn’t been recapped yet), and then it hasn’t made a sound since.
Bit of background, the logic board has been cleaned and recapped, and so has the analog board. It’s been working fine (speaker included) until I had to take it apart tonight.
I have checked the speaker for resistance, and it’s coming back fine. I have checked the cable from the point it’s soldered on the analog board to the connector, and it’s getting continuity just fine. All the pins on the analog board connector looks great.
I also checked the grounding on the Rf shields, and they are all in continuity with each other and on the ground plane with the logic board and hard drive wiring harness ground ( I know sometimes grounding can be an issue).
I get sound out of the headphone jack just fine, so audio chipset is working. Just not the internal speaker.
Any ideas?? I’m at a loss here!
