Hello,
my A190 mcvs recently started to malfunction. It freeze sometimes and after some seconds all the leds start blinking. After a reset it restart but still malfunctioning after some time.
I think the eeprom 24c16 can be defective so I replace it but at this point the module is totally off. I try also to replace the cpu with a new one without success. When I reinstall the original 24c16 the module is malfunctioning but with the new one is totally ko.
I have the complete service manual because I bought it many years ago when I started with eurorack modulars. The components of the schematic of the 190 is a little bit different from what I found in my module, the eeprom was 24c02 and also the eprom is half of memory capacity.
Anyone have a suggestion for troubleshooting? Maybe I have to replace the eprom? My module is old and out of production...
