B&W A7 AirPlay audio board repair?

My B&W AirPlay a7 was working fine until the day it called it quits.

Now I am having a red blinking led.

After the teardown of the device the dsp board has a burned area under the thermal compound.

What I need to ask is if there is a complete dsp board as a spare part or what is the number of this part.
Do you think it can be fixed or it is beyond repair?
Any help would be appreciated.
Thaks for listening.
