Oops sorry about that, I meant to post something on that.
A couple weeks ago I also realized my displays weren't dimming, it turns out there's a small resistor on the back of the display that has to be moved.
Find the area in the image below. It says "Backlight Control" and has 3 rows of resistors.
The top row (R14) says "PWM_MD070SD" and has the resistor.
The next row (R12) says "LED_A" this is where the resistor above needs to go.
Put the soldering iron on one side of the resistor for about 2 seconds, then quickly go to the other side and push it off the pads. It might stick to the soldering iron so flick it so the resistor falls off, just don't lose it. Then solder it to "LED_A" and it'll work. Sorry about this, of course any new ones going out now have been switched over.
Anyone else who has a display from me and it doesn't dim this is what needs to be done.
