I picked up this little dock a while back and it has been a good little performer for charging and casual listening of Apple iDevices. Last night it had a sort of pink fit, turning on and off multiple times, then dead.
After checking the obvious; power supply and several different devices, it was time to disassemble and see what was going on. First trick was how to dismantle the little sucker… I unscrewed the battery holder underneath, moved it aside, and saw that the case was held together with screws from under the speaker grill area.
As you can see the white plastic surround is gently prized off, it is held on by plastic weld posts, and some of these were lost to the cause! The grill is next, again gently prying off with a sharp tool. Now remove four screws holding the speakers and the other four case screws, then pull apart.
It turns out the problem was cracked solder joints on the DC connector (circled below), re-soldering them with a little scrap wire on the PCB to give some mechanical strength, should make it last quite a bit longer.
Here’s another shot, this is the PCB…
and here we are all working once more, listening to some classic music!
