What’s the PNC number?

assume model is D5701-4a

from diag there is a clock module and power board

it could be either or both
the power board has the relays on it to control elements but will also provide a low voltage to power the clock display and electronics to set temp
it is either this power board not supplying power ( look for blown caps etc) or the clock board blown
the top oven seems to be a conventional stat so will not be affected

hope it helps

Hi dave
cannot see any wrong with power module caps dry joints etc

I have not inspected clock pcb

As for top oven / grill you can remove all wires from power board and these will still operate fine.

Power board is just for the main oven.

Clock is an obsolete part even though oven is just over 5 years old .

No one seems to have board in stock not even disrti

Re: AEG OVEN NO CLOCK DISPLAY DS701-4-A

you need to have a close look at the board to try to find the power supply
it can be a transformer , series capacitor or switch mode

if its a transformer you can check primary and secondary windings for continuity, series capacitor are cheap so if its that change it and see. switch mode is more difficult

you could send me a good quality photo of the board and i will look to give you some pointers if you like
