First of all.
Which kind of lunchbox do you use ? I had some trouble with a Bento2 with the phantom power. The power board had some problems and the regulator fired up two times.

Second:
You had some solder joints who look really bad.
You should definitely resolder some points (there are lot of joints where you can see the gold solder pads)
95% of problems are poor solder joints.
Also use some isopropyl to clean the pcb.

Hi TillM

I use Radial Six Pack. I have another VP312DI (Rev. C PCB), VP28's and they all power up fine, so I doubt if it's a lunchbox chassis issue.
And thanks for pointing out. I assumed if I tested continuity with DMM, it'd be a good enough connection, but I will definitely look over again and try re-soldering some points.
