Long story short: I was modding my VA2 Genesis with a CXA2075 .
Thing worked until one day the encoder started to display wrong colours. I decided to check what was going on.
I discovered that a capacitor on the CXA2075 side had desoldered. After resoldering, I hooked the system up and to my horror and surprise, the thing was not booting anymore.
I tried booting Genesis, SMS, SCD and 32x games , all of them failing to boot.
When I turn the system up, I notice some sort of slight "shoosh" at regular intervals(10 seconds approximately).
What could be causing this issue? I really need help here, it was my only working Genesis until yesterday. Any help will really be appreciated.
