Thanks for response. But do you think a offset reference would cause the entire LCD not to display? I would expect wrong segment sequence but it should still be displayed something.
Your assumption is correct! The PCB has provisioning for 3rd LCD supplier which has different pin configuration, allowed by 0 Ohm jumpers. And yes the LCD has driver ST7036 embedded and is controlled by STM microcontroller. For this set up, i am only using pins with 'T' suffix

Thanks and well noted regarding common anode/cathod. Please see attached schematic as you requested. I appreciate your help, i have personally invested with the supplier so i can't afford a loss in NRE.
Hi
Using an existing LCD sample as reference, I have sourced out for competitor design of a similar LCD from another supplier to save on cost. When the competitor samples finally arrived, the LCD would not turn on. All voltages match however I notice a difference in segment mapping. Please see...
