A quarter of LED matrix missing 2 colours

Post by blueboat »

Hi Guys,

I have a 32 x 32 RGB LED Display and RGB Matrix Hat with Real Time clock.

I am missing 2 colours in the whole of the top right quarter (only displays red in top right 16X16 section).

I am wondering if this is a fault in display, Hat, or my soldering of Hat headers. (and how I might tell?)

Thanks for any input.

post some pictures of your soldering. Also, it may be a flaky ribbon cable connector. If you put the connector on a work table, holes down, and gentry tap on the top with a hammer, it will help seat the pins.
