BlackVue DR400G-HD Lens Cleaning and Battery Replacement

After an infamous thread on RedFlagDeals regarding an insurance fraud scam foiled by a person’s dashcam, many people started installing them as their own insurance, or simply to point out and ridicule poor drivers.  Sometimes people catch some crazy events.  I ended up purchasing a BlackVue DRG400G-HD from a group buy.  It was one of the better cameras at the time, 1080P recording, GPS, and a nice sleek build.  There are more affordable ones out there now such as the G1W which I have installed for my family members.

Most recently I captured lightning striking a utility post and it took out power to a traffic intersection.  When I went to check the footage, I found that the image quality was very poor.  I knew it was getting worse but always attributed it to a degrading sensor due to summer heat.

My camera also had an issue shutting down — it would no longer say “BlackVue now shutting down” when the power was cut.

Instead of tossing it for a new one, I opened it up for a little bit of maintenance to get it running like new.

USB Stick Repair

If you bumped your USB stick by accident and it’s intermittently or not detecting at all, don’t fret!  It’s likely a damaged solder joint. If you apply a bit of force to the stick and “bend” it while plugged in, and it starts working, crack it open!  Less than five minutes of effort and you’ll Most Likely(tm) have your precious data back.

USB Stick

Four shiny new solder joints brought this ‘dead’ stick back to life.


Pry open your stick – this one is a cheap plastic one that came apart with almost no effort. Examine the 4 solder joints to the USB connector.  You can probably see a crack without the aid of a magnifying glass.

Pull out your trusty soldering iron and reheat those joints until it is shiny.  You can add a touch of solder if it’s not reflowing easily.

Plug in, and done!
