That's what I thought.
We see (and repair) this
a lot. The problem is on the control panel, which
we regularly repair nationwide by mail for $39.95 postpaid in about a
week.
At
our Web site, you can get details of our service, plus we have a video
available showing how to remove a typical
over the range control panel assembly in under 5 minutes.
This light failure often
occurs when a bulb goes out and the filament
shorts, or when the bulbs are removed or installed without first
unplugging the oven from the power line. Either can cause such a
failure on the controller.
This can often also
affect the exhaust fan operation, too. The lights and fan can be
inoperable or stuck on too.
Feel free to contact me directly (and please remind me of your
full model number) for more information & help.
We're
happy to help you with free advice and we'd appreciate your
thoughtful rating of our answer.

Well, at least the backlight inverter board is working (it is one of the part that commonly failed), the problem can be in the main control board.

Check your connections and scart leads, take them out and put them in again. It may be a loose lead or maybe a faulty lead, swop them over to see.

You need to find out if the power supply is putting out 24vdc for the backlight inverter board, it can be that the inverter board has short circuits which will cause the 24vdc to go into shutdown to protect itself, you can disconnect the power cables to the inverter board to see if you will get the 24vdc back.
