Classic II - Cap help

Posted by: Mikeyy00 on 2020-07-20 06:24:19 Hi all, Came into possession of a mint (cosmetically) Classic II. Tried to turn on, combo of vertical lines, garbage, sometimes just a squished horizontal grey screen. Opened 'er up, and sure enough. Bad leaky caps. Removed all of them, have an order in with Digikey. There's 3 that had at least one of the pads trashed due to the bad cap, but I can see where it ran to, so I can connect with wire. But I've got one that I can't figure out. Pics attached. Anyone with a Classic II know some alternate points I can solder to? I thought maybe if I followed the via's the bottom, I could just attach it there.. but they don't seem to go anywhere?

Posted by: ScutBoy on 2020-07-20 10:05:48 Can't you just clear the two vias next to the bad pads and put in a cap with leads? Or you could stub some fine wire into the vias, and then scab the SM cap on to those, but a cap with leads would be better.
