What does a blank or flashing display mean?
In one sentence
Start with the food, not the panel: a dark display on a cabinet that is still cold is usually a panel or supply fault, while a dark display on a warming cabinet is the bigger question. — Viking Repair Denver Pros, (720) 903-2603
What it usually turns out to be
-
Nothing is reaching the cabinet
A built-in is quiet enough that a tripped breaker can go unnoticed for half a day, and a panel going out is often the first thing anyone spots. Look at the breaker serving the kitchen, and open the door to see whether the interior light answers. Dark panel, dark light and a temperature on the way up is a supply question before it is an appliance one.
-
The panel itself has given up
What you press and read is an assembly in its own right, and it can go dark, light unevenly or stop responding to a press while everything behind it carries on as normal. That is the kind version of this fault: the cooling never stops, the temperatures hold, and what has to be changed is the thing under your finger rather than anything in the machinery.
-
What drives the panel has stopped
The panel is a messenger; something behind it decides what gets said. Lose that and the symptom lands on the front of the cabinet, because the front is the only part you can see. The evidence is usually elsewhere: a fan that has gone silent, a compressor that never starts, a compartment drifting while the face of the unit says nothing at all.

Something was disturbed near the unit
Doors get rehung, cabinet panels come off and go back on, joinery changes around a built-in that never moves. A connector nudged during that work can leave a display half lit or blinking, and it has nothing to do with the age of the machine. If anyone has worked near the cabinet lately, that is worth saying when you ring.
What that means for your kitchen
Flashing is a different message from blank. A panel that blinks is asking for attention rather than telling you the fault, and guessing at what it wants is the expensive way to find out. Photograph it, note what the compartments are reading and when the blinking started, and leave the interpretation to the visit. The rule underneath all of it stays the same: if the food is cold you have time, and if it is not then the panel is the least of your problems.
Follow-up questions
The panel is dark but the food is still cold. Can it wait?
Usually it can, because a cabinet holding its temperature is doing the job you care about, and a dead panel mostly costs you the ability to see or change a setting. Book it rather than living with it, though: with the display gone you have lost your early warning of everything else. Viking Repair Denver Pros, (720) 903-2603.
Does a blank display mean the control board has gone?
Not on its own. The panel, the connection behind it and the supply into the cabinet all produce the same blank face, and every one of them is a cheaper answer than a board. Order matters here: a board is confirmed by ruling out what it drives, and that is the work the $89 visit pays for.
