[Circuit Diagram for Phihong PSM36W-201 Power Supply?]

Finally got around to fixing this. I can confirm that it is the C4 Capacitor, regardless if you see it visibly burst or leaking. Mine looked completely fine but I followed the instructions from this post and changed it. Purchased a soldering kit from amazon for $30 and a set of 10 x 100uf, 50 volt capacitors also from amazon for like $2.

 

I have 0 experience with soldering and managed to fix it on the first attempt so pretty much anyone can do it.

 

Everything works fine though I'm not sure how hot the power supply normally gets because I never cared to check before it stopped working. Perhaps someone can confirm that it's warm to the touch and even warmer when in use...but not too warm that I can't comfortably hold it with my entire hand for as long as I want.

 

Thanks to drueppel and anyone else who contributed in helping others repair their power supply.

Klipsch iGroove HG model 1006519 power supply is a PHIHONG PSM36W-201

Can usually be repaired by replacing the small 100 uf 35 volt electrolytic capacitor C4 (next to the top of the large electrolytic capacitor)

See the PSM36W-201.jpg file attached. Observe correct polarity. Negative is toward the more open area on the circuit board.

100uf, 50 volt is okay. $1.50 at Radio Shack. The connector pinout is two ground pins closest to cord. +18 V on left top, -18 V on right top (with cord aimed down) All you need is a small soldering iron, solder sucker, and a bit of solder. Good luck.

 

Hi all, same problem here but having 0 experience or knowledge on how to even troubleshoot to see if my C4 capacitor is the fault I would like to ask you guys for help. I do have a multimeter at home and if I figure out what to fix I can definitely run out to grab a soldering iron and the required components.

 

I popped the adapter open and that's where I'm sitting at right now.

 

Thank you.
