I recently picked up a mint Sonos bundle, ZP100, bridge unit & controller for $35 at a salvation army surplus store. YES! What a greet deal your thinking, after testing at home, the only thing wrong with it is that left speaker terminal post was snapped off. Every thing else is working flawlessly.
I decided to start a thread on doing general repairs on your SONOS equipment.
Hence, currently I am searching online for original SONOS speaker terminals and have found that there is very little replacement vendors out there.
But, if anyone out there who might know of a good resource, please post those links here and I'm sure this in hand is common and will help the next person. :))

However, you could consider switching them for goldplated banana contacts or similar, I assume it's just a round hole in the player? And you can probably get these in any assorted electronics shop.
My logic with tech support is;
Their paranoia is unfounded. If I want to copy their system, I would buy a new one and clone it.
If I am a hobbiest, and I want to repair my Zp120, why can't I buy the most failed part, the power board?
I now have three Zp's and all have power transistor issues. I would prefer to replace them with new boards. Out of stubbornness I will eventually map the board and buy the components. I need a new hobby.
I like the idea of a forum associated with repairs and parts.
Out of all that I've repaired, not one has had the same root cause.
Initially some of the power rails were not coming up. But now with that fixed, the unit still doesn't show a whole lot of life (though the white LED comes on now - it didn't do that before).
Since somebody said they'd repaired a few units, I wonder if they might share some details on the root causes, and how they might go about determining if the system is trying to boot, stuck in reset, etc.
If I had a schematic, I would fully check the power+reset sequence, but a bit hard to do it fully without schematic.
Is there a serial port or anything to check for boot-up messages?
What and what can I check to see what's wrong and to fix?????????
For self repair searching the web is your best bet, the built-in forum search is poor, and you'll find some good topics and tips.
I've been repairing digital circuitry on and off for nearly 20 years now so was well placed to repair mine myself but I was aware that Sonos don't like you doing that and it's an expensive bit of kit, so I got one of my Play:5 Gen 1's fixed by Sonos 8 years into it's life. I'm not prepared to go into detail of the deal publicly because I don't know if it's something I should share. Needless to say I'm still a happy customer.
What is the most common fault that water would cause?
If the unit is powered during the flood, there could be massive damage due to stray conductive paths. If the unit was more or less fully wet, rinse the unit with clean water. Impure water can result in chemical ractions that will corrode metals -- causing them to disappear into a green mess. Sugary drinks are very destructive. Fully dry the unit as soon as possible.
Note that SONOS will not repair a unit that has been opened. If you have decided to DIY, then continue.
Open the unit and, if it had been thoroughly wet, give it another flush and dry. Clear water in an unpowered unit is not much of an issue. One should see what happens on the production line -- there are all sorts of nasty liquids. Try not to flush debris into controls and switch contacts. Thoroughly dry the unit.
I don't recommend applying power until the internals have been given a thorough flush and visual inspection. Look for deposits and mechanical issues. Now, you can power the unit and fully assess the damage, if any.
You'll need to be capable of component level diagnosis and repair because there are no complete assemblies available. Things can become very complicated if you need to replace any of the FLASH RAM because you'll need to program the replacement.
Once rinsed low pressure compressed air or canned air (warm it often) will do to remove the water. Pay particular attention to the spaces under components, get them very dry.
There are repair posts around here with parts sources and tips but you'll have to dig for them. If the forum search fails try a real search engine and restrict it to just this site.
Stanley_4's comment about using compressed air to remove the water is helpful. Mechanical removal of the water is better than evaporation. Pay attention to the low pressure comment. High pressure blasts can blast components off of the board along with the water.
