A Dead Security Camera Was Brought Back To Life

A guy brought this camera for repair and he explained that the camera powers up on a USB charger and sometimes the camera powers on but most of the time it is dead.

It is a cheap china made camera and deep in my mind I have some thoughts; either a bad power adaptor, colder soldering joints at the power port or simply both.

It was very easy to open the device and take a look.

First thing I saw was the rotating motor but the problem is beyond that stage.

When I got to the board and took a closer look at the there I found the problem right away. Could it be that simple?

I saw some bad cold soldering joints and right away I addressed that by adding fresh solder to every connection I see on there and as seen in the photo, there are not many on that board.

I put everything together and powered up the camera using my power supply on my work bench and it worked like a charm.

I called the customer to come and pick up and to bring the main power supply but somehow; he came to the shop without the power supply. I showed him that it is up and running but it might not work in his place simple because of a bad power supply.



The customer took the camera and few minutes later he came back and told me it was not working but still did not bring the power supply with him which annoyed me big time. I told him to try out a new power supply and as a good gesture I gave him one of my used power supplies that I have in the shop to try it out.

He called me later on and said that he tried the power supply I gave him and it was working like a charm.

Mission Accomplished.

    I can't think of why someone would repeatedly refuse to bring his matching camera power adapter in other than that it must have been stolen because his camera didn't work to see it happening?

    Good and fast repair work,one thing we techies must do is to know well our clients psychologically,for we deal with different people with
    different stroke.Some behave irrationally.
    However does any one have idea about dell1220 projector with power led blinking?

      Imoudu: it was an easy task to do in less than five minutes.
      when the laptop power led blinking (you mean the charging LED)? check the insided charging port and see if enough voltage is going through and if yes then check the battery voltage to see if it is charging or not? randomlly check power supplies on the mother board and make sure you have the other voltages present.check for mosfets shorted on the main power rail.
      have a blessed day

    I also laugh . All client are the same around the globe. Sometimes you end up wasting so much fuel to prove the left PS is faulty.
