Water leak on Denon Receiver - Advice please

[Deadbone]

Moderators, Please move this post if i have posted in the wrong forum.

I have sadly woken up to find my Denon AVR-2809 Receiver sitting in a pool of water. My air conditioner mounted on the wall above my receiver backed up overnight causing a build up of water to drip on my amp. Looks like about a half a cup of water has made it inside the receiver at the most. A couple of cups worth have landed around and near it.

On discovering this i have done the following:

• Receiver was not power up so i unplugged it.
• Unplugged all hdmi, speaker and power chords.
• Dried outside of receiver.
• Dried all input sockets and plugs on back face.
• Placed on towel under to absorb any water leaking from chasis.
• Opened outer casing to inspect amount of water inside.
• Small amount of water on back half of inner components and below. (very hard to see)
• No water damage on the front half's inner workings.
• No water damage on front lcd or face
• I am going to leave until dry for at least a fortnight until i try powering it up (Yes? / No?)

Anyone here had any similar tragedies?
Any advice on how to best deal with this accident would be greatly appreciated.

Read about using a hair dryer on low temperature (Yes? No?)

Don't think i will have any luck with insurance being the air-con.
Also going to check what my options are for accredited Denon repair person to look at it.

Thanks in advance
