I have 2 SB3s which stopped being reliable and this thread caused me to
try them again using them with a power supply I know is good, but their
problems were deeper. 

One freezes, then reboots about once an hour when playing, the other
just dies after a little playing becoming completely dead, to the point
you need to unplug it for a little while before it will boot again.

When I first put them away I'd found (and luckily printed) a logitech
forum post which only seems to exist currently in a google cache of a
static ip at the moment.

The thread mentions changing two of the caps:
"Replacing C16 and C20 solved the issue in my case." 

or more elaborately:
"I ordered a bunch of WX and WT series surface mount capacitors
(Nichicon brand) from Digikey and installed them this weekend. Took a
couple hours and i don't suggest the faint of heart to attempt the
repair. One must be careful not to lift the solder pads with too much
heat! I replaced all of the capacitors that read questionable on my ESR
meter (about 10 of them), and the unit works flasslessy again! Been
playing for 72 hours straight without no reboot or hiccup. In the past
the unit would reboot within 2 mins.
In summary:
The issue was not the WiFi module, it was the surface mount capacitors
drying up over the years, causing points of high resistance in the
circuitry."

I'm not quite to that point, or have technical expertise to achieve it,
so I'm stick with my existing plan of picking up old SB3's on the cheap
(getting a backup SB3 on Wednesday for $25) and maybe making the jump to
pico players once all my ip3k players are all dead.
