Hi Izzy,
Welcome to the forum!! Sorry for the delay in getting to you!
From a look around on the net, it seems like the firmware on the resin printers are a little different.
I came across this set of instructions that has worked for a few Makers:
(In regards to the LCD not showing any images it looks like they break up assests as they are loaded into the machine, this might be what happened)
Just an update - I am printing! So here’s what I did just for those of you who may have come across the same issue. (this is essentially similar to u/Tovrin’s fix but expanded for clarification)
NB - I am a Mac user
1 - I purchased a couple of San Disk 32gb USB sticks. I did not format them as they came reformatted as FAT-32.
2 - Download the latest firmware as per 3D Printer Slicer Software& Firmware Download - Creality 3D by opening the page, and clicking the “Resin Series Firmware” section and then the + to the right of LD-002H to reveal the firmware list and clicking on & downloading the firmware dated 16 nov 2021 LD-002H.zip
3 - Inserted one of the new USB sticks into the computer and then open the LD-02 zip file (note that the unzipped folder is named LD-02 not LD-002)
4 - I then moved/copied the contents of the folder LD-02 (all four files - update.LCD, V3_P318…, L V4-UI…, chuangxiang…etc) to the USB and then ejected the USB once the files were copied
5 - IMPORTANT! With the PRINTER OFF - I inserted the USB stick into the printer and then switched on
6 - The printer will beep loudly several times as it processes the files on the stick
7 - The display will then come on
8 - Remove the USB and then restart the printer
9 - Insert the USB stick and then tap PRINT on the printer - you will now be able to see a list of files
10 - Tap the BIN file and tap the PLAY icon to “Print” the file
11 - Turn the printer off, and remove the USB stick
12 - Turn the printer back on again and check the firmware has been updated
(don’t try and print the CBD file from the USB - it won’t recognise it)
13 - Insert a fresh USB into your computer (or re-format the previous one) and save a file DIRECTLY from Chitubox to your USB stick - the file should save as a .ctb file
14 - Eject the USB from your computer
15 - Turn on the printer and insert the USB - you should now be able to tap Print and see names and thumbnails of your .ctb files - tap the file you want and start printing!
Hope this helps someone! Cheers!

In regards to the UV backlight not being as crisp, it sounds like it might be deteriorating - If you’d like to get back to printing with the same quality that you had originally I’d have a look at replacing it!
Unfortunately the resin printers aren’t able to interface with a PC running Pronterface or Octoprint to debug.
Let us know how you go!
