Issue with Speaker - Not covered under warranty due to water damage

[Dannyboi]

Good afternoon,

Apologies if this is not the right forum to ask in. Not really sure where to go here.

I purchased a Sony GTKXB5B Speaker and it decided to stop working 6 months after purchasing it. Upon returning it to the shop, they confirmed that it does not work due to water damage, however, I know for a fact that it has been kept indoors and out of the way. They sent me this pic. Would anyone kindly confirm for me if this indeed shows that the item has been damaged due to water, or are they just trying to pull a fast one?

Very much appreciate your help with this.

Looks more like a burn mark than water to me. It could be from liquid leakage from one of the capacitors but water generally results in corrosion of all the solder joints nearby.

The white deposit on the PCB is may be due to some salt (hard water leaving a salt residue after drying) but the amount of deposit is extensive and the water may be sea water (guessing by the extent of the deposit) which is unlikely.

There are brush marks on the deposit.

Clean water (deionised water can be used to clean a PCB; Ethyl alcohol and isopropyl alcohols are also useful) leaves no reside.

I guess that the PCB was not cleaned thoroughly after manufacture.

I took the 'white deposit' to be light reflecting off the board and the problem being the black area between the heat sink and black electrolytics. Can you clarify which of us is correct please Danyboi.
