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.
As for the power supply board, the C4, R1, R2 capacitor is blown.
The power supply listed as MFW-15_POWR v2.1 and link to the power supply board https://www.flickr.com/photos/156489319@N02/.
I found several links that showed how to replace the capacitor to fix the hum but not to replace the other broken capacitor. Can someone point out what is the value of the R1 and R2 capacitors and which capacitor I can replace it with?
Any help would be appreciated thanks,
