Bin it or live your life wishing you had binned it

hav it
pcb in the icos or not much better. Big black box if a recall dont forget the jumpers lol
Thats not my experiences!
I would say that is caused by water leaking from AAV or pipe above dropping onto the connector into display PCB where there is a back to back PCB connector.
That may have also taken out the main PCB but it might have survived.
New ones might need jumpers setting to your model.

Dammit always forget that
as agile says check the connecton to the user interface jack from the main PCB for corrosion, this kills em
Must say tony its my experiance that the main PCB rarely if ever survives this blatant design failure lmao
Ideal icos and isar sucks a really big fat one

The design failure of an electrical part under an AAV does not stop there!
The main PCB does not have any protection against overcurrent in the supply to the display module and as you say it often overheats and spoils the main PCB.
Two design faults in one!!!
A cynic might say this is part of the design just intended to sell more spare parts !!!

I agree, water leak (condensate, system or domestic) is usual suspect. Check the violet wiring harness between the user and main PCBs for continuity first, then clean up the interconnecting card (the bit the user display PCB plugs into). If it was the user display that was not communicating with the main PCB I would expect a red dash (or green on the HE models)
