Very nice video. Thank you very much. However, I have got an issue that, no power is there when I connect to power outlet. How to check or repair? If you kindly suggest?

[@GOODTIMEStech]

Hi, Please check the power adaptor output, most of the time copper conducting wires inside the cable of adaptor are open usually near the adaptor where it comes out or at the connecting DC pin which is connected to the soundbar, if there is output from adaptor then need to check power switch, fuse and other components on mainboard. Thank you for watching the video, have a GOODTIME....

@@GOODTIMEStech Thank you so much for your response. What I have noticed is, the power comes back without doing anything if there is a spark while connecting the plug into a wall power outlet, and goes off the same way, if there is a spark. What could be the reason for this? If kindly suggest. A big thanks nevertheless.

Optical port flap broken. No connection to optical speaker

[@GOODTIMEStech]

It should work if the optical output from some device like TV or DVD/Blu-ray device is connected.

My soubd bar is dead doesn't switch on.

[@GOODTIMEStech]

May be the power adaptor have failed, in many cases I have seen the adaptor cable faulty, if there is voltage output from adaptor then need to check inside circuit. Thank you, have a GOODTIME.....

[@madhankshatriya7271]

Adapter is working fine I can able to smell like burnt near the power pin in sound bar.

[@GOODTIMEStech]

@@madhankshatriya7271 May be the power socket has burnt or there is dry solder at power socket joint, need to check.

Bluetooth button is not working

[@GOODTIMEStech]

Hello sir, does the bluetooth button work if slightly hard pressed ?, you can try the method shown in the video, first short the switch terminals, if it works then you can clean it as shown in the video, please take care and follow method as shown. Thank you for watching, have a GOODTIME.

[@venkateshthota2996]

Hard press of Bluetooth button worked but do we have any permanent solution?

[@GOODTIMEStech]

@@venkateshthota2996 If hard press works, you can do as shown in the video or you can replace the micro switch or you can get it replaced by a electronic technician, permanent solution is to get a good quality micro switch that are used in high end devices but it is difficult to get, i will update to you if i get one or the weblink from where you can buy, but it will take some time.
