The thing that looks most suspicious to me is the brown vertically mounted cylinder (capacitor?) northeast of the gold horizontally mounted cylinder (capacitor?). It's marked 33116 V2 EKU with an RDE or ROE logo. It looks like something might be seeping from the base of brown cylinder. It could also be discoloration on the board but I've read that capacitors are typically suspect in these applications. The other concern is a number of solder joints have a brown tint. Is this an extra dose of protective coating or do solder joints discolor with heat? Otherwise nothing looks burned or overheated in any way I can tell.

What are the telltale signs of burned devices? Any advice on how to identify bad solder joints?

Thanks,
