[QUOTE="IanCT, post: 157404, member: 6074"] LOL no that wasn't it. :D Believe me, I wish it were. I did figure it out though. Turns out when I pulled the bottom casing off, it wiggled the headphone PC board and loosened the solder points on the board from the dual headphone jacks causing the problem. I tried to resolder them but the traces had pulled away from the board. After a few hours of searching the internet for schematics (found a website with lots of REAL tech manuals, not the lame user manuals) all I could find was a general picture of the headphone board, not a wiring diagram so I could bypass it. I wound up studying the PC board and the wiring assignments and soldered a jumper across three pins from the ribbon connector on the board itself and the sound has been working ever since. Headphone jack will never work again but that doesn't bother me one bit, since I never use it. :) It's in my daughters' room now as their computer for kids games. And they "must" have sound... :) [/QUOTE]
