99.44% of he printing issues you described are LCD related--they wear out with disappointing frequency. Currently I have two "just-n-case" spares in stock.
In their defence, Elegoo has never promoted or claimed the built-in "Exposure Test" to be a "Screen Test"--that said I have never found any use for it at all--even as an "exposure test".
The owner's manuals I have seen have only provided a most cursory explanation of it's initialization and existence; and no real description of it's supposed utility...
