@ khron. So hook the power supply board back to the amp and power it on to check correct?

Re: Av123 MFW-15 power supply problem



I'm sorry, I'm fairly new to this, do i have to hook up the power supply board back to the amp and power up to do the volt measurement? Or i just measure without it?

And by measuring it, the black com will be on ground and the red cable will be on the point you going to test?...

Sorry for the late update. Can this power supply be fix or salvage?...

Yes sir, i'll update it tomorrow currently at work. Thanks for the quick replied.

Hi, I recently bought this sub. However, the person that sold it told me that the power does not work but the sub is still usable if I hook it up to a separate amp. I was able to hook it up to my Inuke6000 DSP and the driver works.

Turning the power on the sub and set it on auto will lit up the green light but If I i select auto it will lit up the green light for a short period of time but shortly after that, it will turn back to red.

I also smelled burning smell inside the of the sub. I opened it and discovered several capacitors burn/ blew up.
