Re: Polkaudio DSW PRO 500 not switching on solved

Its working.

I finally got it working.

Originally, it did not power ON at all.

I replaced all the components in the burnt sections as shown in the attached pics.

The only components I could not get were the two resistors right next to the output connector. I first used a 300ohms 5 w (the blue once in pic) but they were heating up too bad (the amp was working, but I was afraid they will blow up). The schematic diagram shared by a member above shows these to be...

I changed some diodes, capacitors, ICs and resistors.

Now the amp powers ON, led is green. But the two resistors next to output plug heat up a lot and i am afraid there is some underlying issue and they will blow up again.

I did not play the sub much, but...
