Not All Lines Lighting Up

[PurelyAbrasive]

I am having an issue where not all the lines are lighting up. Any idea as to what the issue might be?

it looks very much like a wiring issue. you might want to review your wiring, maybe redo it, to see if it solves it.

you could try a test and 'clear' the display using a colour different than black but then you need a really good power supply as it will consume a lot of power. for a small test it should be fine. look for this line: display.fillScreen (display.color565(0, 0, 0)); - or something similar.

good luck

I have checked my wiring quite a few times and I have even following the Brian Lough wiring and I am still having issues. This is a new board and I am wondering if they changed the drivers on the board. Below is another image that isn’t showing up.

I would triple check your wiring again, I had a similar issue and thats what it was, sometimes the Duponts dont make enough contact with the pins, try wiggling them while the screen is lit to see if it helps

I had similar issue and was able to resolve it by adding the below code Try adding the below line display.setMuxDelay(1,1,0,0,0); I added this under void setup ( after the lines Serial.begin(9600); and display.begin(16);).

thanks for sharing. hopefully this solves the problem for other as well. I have 2 different setups but none show this sort of issues.
