Bigstone C300 LCD

I am still riding a pretty old e-bike which uses a Bigstone C300 LCD display which needs to be changed.
Apparently this item cannot be found any more in any store.
Any idea about a compatible one ?
Thanks much

Not likely, but you never know.

It may be easier to repair the broken buttons.

The buttons are not the issue. Sometime the unit would not switch on...
(may be related to the button, though)
Thanks,
