You've verified that the displays are connected to the TFT rows of pins, and not the OLED ones? Can you post some clear photos of you wiring?

It's hard to tell from the one shot, but you've taken care to have each end in the same order?

To shift slightly. What you mean by "won't light up" is that the backlights aren't coming on? Or the backlight is on and you don't get pixels being drawn?

I don’t get any respons not even a little flicker of light from them and yes they are in the same order all the way through

My next step would be to redo all the soldering on the headers (including the Pi GPIO header).
