    Hello there!

    Please note that contrast voltages for both displays differ, as C12864WC calls for around 10.3 V, while C12864LZ calls for 8.5 V. This may be why you are seeing one display work perfectly, while the other is barely visible. This information is available under the electrical characteristics table on their respective datasheets.

    Like you mentioned, I would try to change the electronic volume for the C12864WC display, and see if that makes any difference in its appearance. For command (18), try manipulating the 2nd byte hex value (Electronic Volume Register Set) while staying within its parameters (0x00 – 0x3F), and hopefully that should do the trick!
