ZP80 Power Supply

A friend gave me an old ZP80 he had that didn't power on.

I opened it up and there's a chip on the power supply that's blown up. The top of the IC is gone so I can't look up the part number. Curious if anyone has high res pictures or knowledge of the ZP80 power supply so I can replace the damaged parts?

Thanks.

Hi guys,

Seems that this thread is a bit dead. Following the suggestion above, I tried the Fairchild FSDM0265RNB / DH321 VE52 trail and it seems that it's not the one I need. Is there an older PSU board revision (which i might happen to have) where a different part was used? i need one that will fit with the following pin-out:

1 NC
2 GND
3 Vcc
4 Vfb
5 NC
6 Drain
7 Drain
8 Drain

In fact, maybe all I need is to match pins 2,3,4,6,7,8 and can work around the rest somehow...

Any help will be much appreciated!

My Sonos connect power board uses a 5M0165R if that helps?

My out-of-warranty Sonos Connect went "lights out" last month. Upon taking it apart, I saw a few components on the power board that looked fried; the 1800uf cap, 2a fuse and 120k resistor, the 5M0165R chip.. possibly others. I think they are all replaceable but i'm not great with electronics repairs... As can can be seen printed by the output wires on the power board, it's basically just providing a regulated 3.3v and 14.8v DC feed to the main board, so i found a lower tech solution.

I han old 12v AC DC adaptor lying around (i think from an old wifi router) that I thought I could try for the 14.8v feed and I seperately purchased a 3.3v AC to DC adapter here..

I cut the plugs of and soldered the connections direct to the motherboard molex connections. I used the 12v adaptor for the 14.8v feed and the 3.3v adaptor for the 3.3v feed.

Red: 3.3v+
Black 3.3v GND
Yellow 14.8v+
Brown 14.8v GND

I wasn't sure if the 12v input would provide sufficient power, but it's been working without fault for over a week now.

The downside is that i now have to use 2 plug sockets to power the sonos now, but i can live with that
