i had the same problem with my DSR9500VIACI, and also other DSR9500EMVIA. I had nothing on Display (completely dead), but got them both back to life by:-
1. Re-writing channel list previously saved to pc with Semco.
(clock then came back)
2. Re-writing latest EMU vers. 8.0to get back s/w vers 133 with conax included.
good luck!
