Matt,

Yes, the Bridge/Cap is the most common issue that causes resets, but there are other things that can also cause it. Such as, look at your connector J101 and make sure it's not burnt or heat damaged. It can heat damage like you sometimes see on GI connectors. You could also have a cold solder joint on the male pins. I'd have suggested you wiggle the plug to see if it affects the problem before you changed the bridge/cap. Check Fuse F113 with your meter and make sure it's not bad or blown.

It's also not uncommon to need a jumper run between BR2 + to capacitor C5 + and - to -. The traces and hole plates can be damaged easily. There are also top side traces on those components and you may not have gotten good flow through to the top side. You can test for continuity with your meter from BR2 + to C5 + and - to -, but I've had instances before where I got continuity, but still wasn't getting the voltage. Running the jumper wires cured the issue.

Beyond that, there's a voltage regulator, but since your board was working with resets before you did the work.....your issue is most likely in the continuity between components you replaced.
