Xbox 360 motherboard question.
Opened up an Xbox 360, never opened before, had RROD. Did the fix and when I was replacing heat sinks, noticed several capacitors were blown. Ordered new ones and replaced them...now problem is a couple of them are loose and don't seem to want to hold solder, I did have to push old solder thru capacitor hole to get new capacitor to seat. Desoldered the half held capacitor and noticed the ring of cooper looks to be gone. This line of capacitors look like they are not touching any line and can't figure out where to solder hook into. Does anyone know does board have a negative/positive side? Or what I can do? Capacitors are 2200uF 6.3V. Any help would be appreciated. Thanks.
