Thread: Anyone know electronics repair at all?

I've got this project I've been meaning to tackle and wondered if anyone has any input. I have this old cheapo Memorex ipod dock, the iTrek, which is completely unsupported with no parts available anymore, and the AC adapter prong long ago snapped off inside the thing:



Battery power worked, like, once and never again, plus the batteries were a pain to get out (extraction involved a wire hanger), so that's not an option. I managed to get the prong shards out of the DC-in, and now I'm thinking about stripping the wires and attaching them directly to get power to it, but I'm not sure how to proceed:



The black box with the white wires coiling around is the DC-in. I'm guessing the two strands of the power cord need to keep separated, so jamming them in the 2mm hole is probably not an option*. Could I attach them each to one of the rightmost solder points on the underside of the board? If so, how do I isolate which is which, or does it matter? Would getting it backwards fry the thing? As an aside, I lack the means to solder, so this will probably be an electrical tape and/or contact cement operation.

*It occurs to me that if the center prong in the DC-in is the positive terminal and there's a contact for the negative terminal on the inner wall of the DC-in, maybe I could establish isolated contact by stripping only one side of each wire. Could that actually work? Most likely the black wire would correspond to the prong and the striped one to the wall, right?

I will try to take sufficient precautions to avoid Darwining myself

Could this guy serve as one of my contacts:



When the board is seated, it would normally make contact with one of the battery terminals (also circled). Just need to figure out which wire should make that contact, and where to put the other one.
