Dreambox 7025 problem.

Not sure if anyone can answer this as there are not many with this box. I installed a second "C" Tuner card into the box to help with the recording and transponder issues and it is fine. BUT:I have lost the LCD display information on the box itself. When I turned the box off at night I could see the time and if it was on you would see the channel name etc: Now all there is a white screen. I have tried the LCD menu settings and a few reboots but to no avail. If I reboot the box I can see the Dreambox file booting in the LCD so I have to assume that the display is not faulty. I know it is a longshot but if you don't ask, you'll never know !!!! Thanks in advance .
