Voxelab Aquila Bigtreetech SKR E3 RRF replacement screen remains blank

[WellEnhancer]

Dear sir/ madam,

Recently I started to try to replace my original Voxelab mainboard by the Bigtreetech SKR E3 RRF, partly to fix issues with the original board. I decided to keep the original Voxelab screen. I have been following the steps in the next video: https://www.youtube.com/watch?v=2ytFdP2_Myo, though I do realise this is for the Ender 3. Up to this point I still have a blank screen when I start the printer. I did try to add the lines of text for using the original Ender 3 screen but this doesn't give any results at all. Can you help me out here?

Thanks in advance.
