By on February 23, 2022

A guy next door who owns an olive wood carving workshop brought this speaker system for repair and the issue was power related. He explains that his speaker system goes into shut down a few hours after it has been turned on. He likes to listen to music while working but for the past week the speaker system was dead and needed some attention.

I plugged the power adapter in and right away I could see that it was charging but when push the power button on, it does not power up.

I am thinking about a power switch issue here and there is a quick way to test it out.

I took the six screws off and right away I could see a lot of sawdust in there as expected because it has been sitting in the wood factory for the past five or more years.

I disconnected the two cables that goes to the power switch and connected

them together and right away the speaker system came on indicating a bad power switch and that is a very easy issue to get fixed.

I have plenty of power switches in my shop and right away I swapped the bad switch with a good used one and right away the speaker system came on once that switch was pressed on. 

Of course I went through a lot of re soldering all the cold joints on that board lubricating all the knobs, buttons making sure that all are in good working condition. With an air blower I blew all the sawdust out of the system then put everything back together and called the customer. Everything was working according to specs and to that I could say

Mission accomplished.

    Well done. Just bypassing some components sometimes makes an easy diagnosis.

    The argument to share such simple repairs is always that it is interesting for beginners. Good job no doubt, but the appeal to read about these simple fixes gets quickly lost after reading so many of them.

      It is true that some repairs are to easy and publishing a difficult repair, even one that was unsuccessful, could be of value. An unsuccessful story could lead to suggestions on what might work, and then a follow-up article when it leads to success.

        William: it is never wrong to share out repair successes or failures as long we are learning from them. it does not matter if it was a simple repair or difficult one as long there is a try and effort to make the device work. have a blessed day and thanks for your comment.
