The problem with these displays, and it seems to be common to all the manufacturers, is that the PCB material is too thin. After a month or two, the board slowly bows away from the glass display panel under pressure from the conductive rubber connector strip. Pressing on the top centre of the metal part of the display makes it work again, but only temporarily.
If the LCD module is soldered to another board and the two top screws installed and tightened carefully to pull the bow out of the module it seems to prevent (or solve) the problem.
Mine all failed after a month or so when plugged into a proto board socket.
The only real fix for this display is to redesign the metal cover with a hold-down tag in the top centre, or make it with a thicker PCB that doesn’t bow under pressure from the connector. Until that happens I won’t be buying any more.
No public wish lists :(
