Anyone has a schematic or service manual for any DSW-Micropro subs?

I recently purchased 2 of these 1000’s and both have now lost powering up. Both fuses have been popped. One sub for sure made a large hummm to a buzzzz and then a large snap sound. I pulled the amp plate off this one and found that the 660045-1 board has a blackened area around the lower centre and also around the H4 Cap series pair of the power supply portion.SeleniumFalcon wrote: »Sent..
Wondering I I could get any available schematics
Of this ? Thanks in advance.

I own two Polk DSW microPRO 3000. One of them went bad in 2018 and I sent it off to https://edwardselectronics.net/index.html to get repaired and it worked great. It's still alive today. The other died some time after and it's still dead. Looks like they removed the Polk amps from their repair list either lack of clients or they no longer can.

Not really mentioned on their site, but do they only repair subwoofers?

@SeleniumFalcon - Any chance I could get a copy of the schematics for the DSW-1000? Thanks in advance!

These guys repair Sunfire subs.

Good day! My search for a schematic to repair a Polk DSW1000 has led me here. It seems it has been a while since there has been a post, but I am hoping someone might have the schematic and also notice my post!
Thanks in advice. -

Hi SeleniumFalcon, I see your message for 'Schematic Sent', but I can't seem to 'see it'. There is nothing in my messages or junk mail folder :-(
Any chance of a re-send and maybe how I can get it please?
Oh and so far I have found and replaced a bad 22mf 50v cap near the daughter board, (next to big caps), and found a bad sot-23 diode on the daughter board too. -

Thank you for the schematic Selenium Falcon!
-
You're welcome, good luck with the repair!

So the schematic is described as DSW2/3/4000 and when I look at the component numbers on the PCB like Q4, U1, U2, R22, etc they do not correspond with the schematic which has larger numbers like D600. Are you sure the schematic sent should correspond with the DSW1000 sub?
Thanks again. -
I'll check with a source at Polk.
-
I'm afraid the current engineering department doesn't have any additional information concerning that series. In all likelihood the differences between the various models are some of the EQ parameters and the output stages. Most of the remaining circuitry would be the same throughout. Hopefully there's enough information to enable a repair.
-
Thank you SoleniumFalcon for checking, I will hopefully be able to take a closer look this week. What ever happens though I'll add a post about what I find.

@SeleniumFalcon I also have a DSW1000 in need of repair. Would you be able to send me a copy of the schematic?

Greetings, new to forum. My dsw2000 power supply fried. Need schematic for amp/ switching supply. Polk only had dsp board schematic. Thanks in advance.

Hello,
Welcome to the Polk forum. I'm afraid those are the only schematics provided by the vendor, sorry. -
Thank you
