No Power In Wi-Fi HeadPhone Repaired
A customer brought his blu tooth head phones for repair. As I understood from the customer, he dropped his headphones and now it does not power on.
From the look of it, it seems like a decent blu tooth headphones and worth the repair.
I was not expecting a complicated repair, may be a broken power button or just a loose one.
As I took the ear soft pad off, I could see three screws beneath and I am sure once the screws were off I will be able to see what lies beneath.
There were three tiny Philip head screws and easy to come out.
I could not see any broken pieces which is a good sign.
As I proceeded to the main power switch on that board, I found something that put a smile on my face.
The plastic piece was supposed to be touching slightly the power button but in this case the plastic piece was not even close to that button.
I took off the two screws holding the board, put the plastic piece on the same level with the power key button and then put the board back and tighten the screws. I pushed the power button and the head set came on flashing red and blue so it can be paired with a smart phone.
I tried it on my Iphone phone and it was pairing just fine.
Mission Accomplished.

Vow! That was a very quick and smart assessment of the defect! Only special trained mind can detect it!

Parasuraman: yes it was a quick fix because the moment I pressed the button from the outside, I could not hear the click of the button..paying attention to tiny details fix problems. have a blessed day my friend.

This Sony headphone indeed looks like a decent made headset. Sadly from experience I know that bluetooth devices like TV soundbars have BT modules in them that quit working after a year or so. And after that you need to buy a new complete set bluetooth receiver AND transmitter module because the older models no longer are sold separately which makes it too expensive for any repair! And even the new modules are only warranted for one year because BT modules get quite hot when active!

Albert: it was a very expensive headset that he brought abroad and it seems like he dropped it a lot which caused the power button to malfunction. have a blessed day

Sometimes the best test equipment is our eyes, ears and nose.
