Hello , i have a strange problem... My dreambox 500s was plugged in and playing for some months, one day i unplugged it and plugged a new one for 2-3 days, after that period i wanted to plug my old device . When i did it , i got a black screen , no menus nothing... I can ping it , i can access it with browser with ftp with telnet , but i can't see anything at tv , i tried 3 tv with rca and scart but nothing... i tried different power supply, nothing... i flashed it with pli jade 3 and nabilo darkstar II (both with dreamup 1.3.0.2), nothing... When i plug in the scart , i goes automatically to av channel but it doesn't display anything .
