It only lights up in the morning when starting, then it goes out and doesn't come on again during any other start-up during the day. I specify that it doesn't even light up every morning. Its frequency is 2 out of 3 mornings.

What does it mean? When a light bulb burns out on the short phase, for example. only the light bulb sign with that big X on the screen lights up and does not disappear. But this sign is smaller, surrounded by a circle and the 2 brackets. It lights up and then disappears.

I checked the bulbs and they all work correctly.
