Sega Nomad Help Please

by radiokid Wed May 25, 2016 7:58 am

Sega Nomad bought from eBay. DC socket was pretty much screwed, so got rid of it. Soldered in a new one from PSTwo slim. Worked fine for a bit then went on the fritz again (very intermittent connection which would power off if the DC plug was moved in the slightest). Tried numerous times to fix the issue but no luck.

Now, in my attempts to desolder/resolder etc etc I am now left with the below. I believe what is called the "through hole via" for the solder holes for the legs of the DC socket have come away; I remember them coming out with the DC socket at one point, but cant remember exactly which legs. To me it looks like the ground socket is the only one that still has its through hole via intact. I have also managed to lift the trace from the positive input from the socket to TP201 (I've made a bit of a mess of this as you can see :? ). I have scraped away a bit of the trace from TP202 (Ground) and TP203 (DC plug sense leg I think) in order to somehow fix this mess, but not sure if this will help.

I want to get this back up and running but not sure what to do next. Any help would be appreciated.

Picture one is of the side that the DC socket legs go through, picture two is the side that the actual socket would usually attach.

Yeah so I gave up on the DC input; couldn't get it working no matter what.,so on to plan B. I've connected the 3rd pin (input plug detection) to ground which connects the battery terminals into the circuit. This is usually done by the DC socket when no plug is inserted but since this isn't an option any more I've gone for this permanent solution. I then wired up the battery terminals to 9V DC and switched on, hey presto it worked.

Since my overall plan is to power the Nomad by Lithium Ion batteries this solution will do for me. I may even internalise them in the Nomad body and wire in a new DC socket (somewhere else in the case) for charging the batteries. And since I won't be touching the original DC input pins I shouldn't have any more issues.
