anyone know where I can purchase the motherboard for this model? Logitech does not sell them

I assume nobody sells the motherboard as a spare part? Pity, mine 650’s dead!

Thank you so much for the instructions. Some buttons of my Harmony 650 were not responding and I was able to open it and clean with alcohol the rubber pins and their peer circuit board conductor traces. After that all works as new !
