Are bad solder connections or the memory IC itself. It is best to replace IC with solder pins. Power supply with old power pack from Neato vacuum robot 24Volt 2A.
Hi there, check IC Spanison FL032PIF. Heat with hot air and then power on. if the typical tone comes, replace the chip. Is a main problem of the Cinemate 1SR, same chip installed. Problem, device does not start, no 24V power feedback.
