LED Matrix Display Not turning on

by majoshi1 on Sat Jan 13, 2018 8:42 pm

I am new to raspberry pi.
I am trying to setup the Pi 3 with LED Matrix display.

I ordered and got following accessories (Order Confirmation No: 1632430-0694356359):
1 x 5V 10A switching power supply[ID:658]
1 x 64x32 RGB LED Matrix - 6mm pitch[ID:2276]

Also, I am using Pi Hat.
And did the setup as per following article:
https://learn.adafruit.com/raspberry-pi ... y/overview

I can connect to Pi.
However, display is not turning ON, when I run the test.
Any idea?

Attaching details of my setup.
Please get back in case of any questions.

$ sudo ./display-test matrix.cfg
Using config values:
display_width: 64
display_height: 32
panel_width: 32
panel_height: 16
chain_length: 4
parallel_count: 1
grid rows: 2
grid cols: 2
Press Ctrl-C to quit...

Also having this issue. Have tried 2 different adafruit rgb hats. Using a raspberry pi 3. Tried the demos from the rpi-rgb-led-matrix repo as well as the rpi-fb-matrix repo. Can't get anything to display. Thinking the matrix is defective?

Hi guys, i have some good news, finally can made the matrix work, the code is all right, my problem was the soldering on the HAT, apparently some points were not making the right contact, so check your HAT and make shure it is all nicely soldered.
greetings!!!

Also received a reply from support on my own thread about this and it turns out they sent me a cable that was backwards on one end so I have to flip the cable backwards on one side to get it to work.
