I have a grape imac g3 400mhz with a dvd drive. I think it is called a DV as it has firewire ports?
I rescued it from the trash a while back and put some TLC into it and upgraded it with more memory (512mb) and went from OS 9.2 to Tiger. The Problem is I have no sound from the internal speakers and the speaker jack on the side. No sound on 9.2 and now no sound on tiger. If I plug a set of speakers or headphones into the 2 front headphones jacks, I have sound, but my internal speakers and speaker out jack on the side near the firewire/usb ports are both dead. I used the search feature on the site and found others having the same problem. I have tried plugging the headphone cord in and out of the ports as suggested in other posts to reset the plug, but nothing works. I also notice in the sound settings the only option I have is headphones for output, I don't have a option to select internal speakers. I saw that it may be a board that has broken it's solder that I have to replace?
For now, I have sound by plugging a set of el' cheapo powered speakers into one of the 2 working front headphone jacks. Any help on which board to replace would be great. I did open up the imac to verify the speakers were plugged in. i even unplugged them and replugged them in for good measure. Nothing in the system seemed disconnected. I am also pretty good at soldering so if it is possible I'd love to save money and repair it myself.
Thanks for the help!
