Apple 12" RGB monitor M1296 repair

Hello.
The D920 diode on my monitor is broken. It has no markings, it's made of glass with a single black stripe.
Which diode should I use?
Several diodes on the board look identical but are also unmarked.

Those look like zener diodes to me. I'd try pulling the D909 neighbor diode out of the PCB and measure its characteristics. I'd wager they likely share the same specifications. If you desolder the D920 diode, there might also be some small label on the component body that could help ID it. I wish I had schematics to help you better.
