So here's the skinny. Pulled C19, C25, C16, and C22. Found that a little blob of chip quik on each solder point and a temp around 650˚F worked best while going back and forth and pulling out the box caps with a set of flat nose pliers. When all was cleared I proceeded to apply some flux paste and two nice blobs of chip quik to the U7. Some directions I found online mentioned I could use a low temp when removing the chip so as not to remove the solder pads, but again I found 650˚F to work best. 250˚F didn't do too much. Once I removed the chip, I cleaned the solder pads with a solder sucker and proceeded to add more flux from a flux pen and re-soldered in a new U7. Finally, I put all removed box caps back in their respective positions. Upon firing up the DAC I tested C26 and C20 and now I'm gettings readings of ~2.35v and ~2.25v. I tested L+ and R+ and I'm getting similar readings. I figured that was better than my initial readings the other day, so I hooked everything up to my computer.......... drum roll...... Audio out of both channels! My only worry is that there is a slight imbalance in my voltages. Tomorrow, I'm going to reflow all joints. Anything else to test for? Could I have a bad cap or semi fried cap? I'd think I'd notice physical damage. I'll also measure the capacitance of all caps and see if that gives a clue.
