Not sure about your model but I have a bosch hgs7152uc model. I found that removing two screws and the metal panel in rear of the stove (at top where display is) will provide access to the control panel. There are four screws holding the display circuit panel in place. Two of the screws were not tight which allowed the circuit panel to move backwards when pressed. Tightening all four screws made the display operational again. The screws had lock tight on them but apparently they came loose anyhow over time

TUTORIALS1, If the Bosch fan motorin the back of the oven is going round and
the temperature light is on (normally little red light), but there is no heat
then you will probably need a new oven element, these are generally very easy
to fit and readily available from our website these can be tested with a
electric meter. To gain access to the BOSCHelement you will
have to remove the back plate from inside the oven. Once removed you will see
the fan and element, if you
look closely at the elementyou will
probably see a small hole burnt in it where it has blown. Sometimes however
there is no evidence of a fault but the elementis open circuit ie:
broken inside the element casing, either way it will need replacing. Some
elements will are fixed from inside the oven and some are held in place by nuts
from the rear of the machine. 2, If your BOSCH fan
oven is getting warm but takes a very long time to cook or is burning the food
more on one side than the other, then you need to check if your oven fan motoris working you will
see the blade turning fast if it is ok. if the element is heating but the fan motoris not blowing the heat into the oven then
you need To replace the oven fan motoris a little more
expensive and a bit more involved. 3. If you have the opposite problem ie: your oven is over heating
and burning everything then you will need to replace your BOSCH oven thermostat 4, A quite common and easily overlooked answer is if your BOSCH oven is not working at all ie: no
heat and no fan then the chances are that someone has put the oven timerinto AUTO mode,
simply put oven back to MANUAL mode and all should be working again.
