OK so I took another shot at it. And I got the screen to come on. But it’s just a blank blue screen. And now the number four green LED light is not on. Meaning that there’s a SD card problem. Is that because there’s an external SD card slot on the glcd? Please help
on mine I had to reverse the connections to the adapter board. Easy way is to nip off the keyed section and insert backwards. It is a common issue for the non-genuine boards and took me a while to find it myself.
