YouTube - MiniDisc Repair - Kenwood DMC-S55 - That tricky battery door...

I wrote about a similar one awhile back (DMC-T55) but didn't get a proper video. Now I found a DMC-S55 (late 2003) with the same issue and was able to record and clearly illustrate the issue in a video!


The Kenwood DMC-S55 started the new, round, speaker dock trend that was continued in the T-series and V-series.




Like the DMC-T55 I fixed earlier, there's an interesting hinge system that connects the battery door's positive contact to the board. Many other manufacturers (Sony, Sharp, etc.) just used a rotating, clamped on hinge to connect the battery door to the board.

Kenwood's design has a small "finger" that moves to a connected/closed position when the battery door is closed. What that means is you can clean the visible battery contacts (at the battery door and deeper inside), and still have a power issue.




I used the process of elimination (testing it on the charging dock) to determine the unit was still getting power, but something else was still amiss.

Opening up the unit, I could see the hinge mechanism had a bit of corrosion on it, blocking the electrical connection. One small swab with vinegar (and cleaning it w/alcohol) restored the connectivity and now it's working fine!

Of course, while I was in there, I gave it a bit of a clean and lube, but I'm very happy to have a working S-series (to add to my T- and V-series).

Please check out the video for the details!

Let's cut to the chase: You need/want to recertify your CCIE without taking an exam and you need to do it as quickly and cost-effectively as possible. Thanks to Cisco's Continuing Education program, you've had the option earn CE credits for years, but sorting through courses to find the best use of your time and money wasn't the easiest.
