The LCD of VP Designing PCB-VP12864 is not working.
The LCD PCB-VP12864 is not showing its shape. It shows just like
. . .. .... .. ...

My fixing equipment is remote of recloser of 15kV. And all of things are working correctly. But LCD shows like that. The shape is changing when I push some functioning button.
Please help me how can I fix the LCD? Is it possible to fix? How can I check the LCD, is it works or not?
