I have bought several AXE131 OLED and none are working. They seem to be soldered correctly but nothing. I have put a poitive and negative to the terminals and nothing happens?

AXE131 is a bare interface board. It does not include a display.
Did you actually buy something like AXE131Y ? or did you connect your own display?
Providing 5 Volt power to correct pins should cause "picaxe.com" to be displayed, even with no microcontroller.
Could it be that you connected an incompatible OLED display?
Exactly which display module are you using?

Have you updated the firmware on the AXE131?
Mark, you only describe soldering up the AXE131 kit.
This is the first step in the instructions https://picaxe.com/docs/axe131_firmware.pdf
Have you also completed these other three steps?
2) Download the AXE131 code from this link:
Rename the file to axe131.bas and then open it in PICAXE Editor 6
3) Near the top of the program define either LCD or OLED as appropriate by making sure that one of these two lines is active and the other is commented out e.g.
#define use_OLED
; #define use_LCD
4) For the line_length symbol make sure it is defined as 20 (for 20x4) or 16 for all other screens.
symbol line_length = 16 ; or change to 2
With the axe131.bas.txt program edited and loaded into the AXE131 then, as Hex has already said in post #2:
"Providing 5 Volt power to correct pins should cause "picaxe.com" to be displayed"
