PS: rmrodriges ... this is also appearently your Problem with the Display as well, please check it yourself before modifying it with your multimeter...
Hopefully this helps you!

Yep. it should be the same problem because the vendor is the same.
Did you change the connectors position? Could you post some photos please?

Many thanks.

Hello again,
Yes, for the LCD12864 from bigtree-tech the connectors should have been mounted 180° turned, but here I have a modification.
All you have to do is just to turn the cable connectors 180°.

Still, please do the checks with a multi meter before retrying, I take no responsibility if it is not working for everyone !!
Be warned and measure first before damaging your equipment .
I just know it worked out for me and with the bigtree-tech LCD12864...
In the attachment is a small image, which might help...

Best regards,

Hi there,
As Raisa suggested me, I've turned the connector 180 degress and it's working fine now.

Many thanks Raisa.
