DCC300 Display dosn't light

Good evening,
After changing the gears on my DCC300, and taking care to locate the different connections, the display does not light up anymore.
However, the player works.

Would you have a clue?
PCB of the player?

Hi and welcome,
It could be a power failure issue, either from the power supply of pcb.
Make sure that all is still connected correctly. Otherwise it would require some measuring to see what is going on.

Here is another topic on a 600 with a similar issue. The technology is the same between them.
