Hi, start with the basics first. Have you checked all the cables and connections, especially the one connecting the two speakers and the one connecting the speakers to the pc? Swapped cables?

And perhaps use a different pc to connect? 

Don't think it is a power issue.

What did you do, just before the problem crop up? 

If I remember correctly, when the speakers are not connected to the PC the LED is red (constant); no signal. It does not blink on and off. 

Have you tried AUX in to see if the result is the same?

when i first setup i got the problem, and then i try to take the cable off . re-install the cable and change the position on the exstension , and then everything is good. and it happen again after i turn off the speaker power. and when i turn it on again it happen again, and then same thing .. i adjust the cable change the cable location and change the location on the exstension and its okay again.

and now.. without connecting the speaker to pc just speaker > power , its make the 'tik'tik' sound and turn on and off ( green light/red light) rapidly. 

but i havent try the AUX, mybe tonight . need to buy the AUX cable first. 

already inform the seller the issues, and he said might be socket problem , hmmm

Your video does not show the red light by the way. Just green and blinking (unless the video is not clear).

Assuming the seller is right it is easy to test. I assume you are using the original power cords provided? If yes, then just plug it into another power socket and see if you have the same issue. 

If it is a socket problem on the speaker then you will probably need to send to Perfect Hifi to repair. Since you just bought it, best if you can ask the seller to sort it out for you, especially if it is still under warranty.

yes got few other videos as well, red and green blinking , and yes i using all the original power cords provided by seller, 

too bad the warranty cover is already expired.

tonight i try the (1) AUX , (2) Different power socket . and if all doesnt work i will send it to local audio shop for a repair. 

btw thanks for your help  !!  Like a Star @ heaven Like a Star @ heaven Like a Star @ heaven Like a Star @ heaven Like a Star @ heaven
