Sure this is the failure off the unit but make sure that the step down transformer for the power to the unit is faulty or burnt. If so replace the transformer. If power goes tto unit without display then the processor can be faulty . Change the clock timer. unit if you need the timings.

Testimonial: "Thanks caroldon, but it sounds complicated. How do I check the transformer?"

    Thanks Caroldon, but it sounds slightly complicated. How do I check the transformer? Is it just 4 screws and the oven falls forward?

    Check the power cord , trace it all the way in to the clock board , the transformer must be inthe front end., a multiimeter check will prove it working, an open connection means faulty.Take a try.

Both the top and bottom oven will only work if a time (any time) has been set on the clock. Setting the time operates a contact to switch the power through. The only exception is the grill. This will work even if the time has not been set. So if the oven controls/lights and heating work, to me it means that the clock/timer is half working and the only thing that isn't is the display.
I haven't had the clock/timer to bits but a fellow blogger has said that in some timers there is an electrolytic capacitor that controls the display. When this fails as they are renowned for doing, the dispaly mal functions. If there is one then Maplin have some - VHR41W/43W and DT64U depending on value etc. Let us know how you get on.
If you need a new clock/timer they are around £80 from espares.

We have Smeg DUCO8CSS double electric oven. Bottom oven does not work, clock is blank and fan doesn't work. Top oven OK ! - though usually the fan runs when this is operating.

If the clock is blank, then the main oven will not work, as the clock timer is linked with the main oven.
You need to to get the clock working, or you will not be able to use the main oven

Just brought a bosch oven and there no life in the bottom oven

If it has a timer, then make sure it is set manual and not auto, or the oven will not work.
Try pressing 2 buttons at the left of timer and one button on right of timer to set it to manual, if it does not work this way, then try another combination of buttons.
Hope this helps.
Plz rate my solution.
Thanks.
