Update:

Recently, we have done the second test for PID: 2345. I found that is the RGB Matrix HAT + RTC caused the problem.
I have changed the RGB Matrix HAT + RTC board, same configuration, and set up as Unit 1, it works.

Unit 2 ( second test): https://drive.google.com/file/d/1rTc8E_ ... sp=sharing
Could we get the warranty claim for the board?

Please post a photo of your soldering job on the headers pins for the first HAT.

Why are you using jumper cables vs. attaching the HAT directly to the Pi?

Please flip the HAT over and take another photo. The soldering in question is on the opposite side shown. Thanks.

The photos are a little out of focus, but it does look like soldering may be an issue. Please see here for common soldering issues:
https://learn.adafruit.com/adafruit-gui ... n-problems

Try inspecting all the pins and reflowing any that may seem cold soldered or insufficiently wetted out on the pads.

I have changed the RGB Matrix HAT + RTC board, same configuration, and set up as Unit 1, it works.

What is the "Unit 1" here that works?

Try connecting the HAT directly to the Pin instead of through this ribbon cable.

Sorry for the information that misleads you.
On that days, I have replaced a new RGB Matrix HAT + RTC board , I configure it the same as the configuration with Unit 1. The new RGB Matrix HAT + RTC board function well.

Is the only difference between Unit 1 and Unit 2 the Matrix HAT? All other hardware is the same? Same Pi, cables, matrix, etc.

If you haven't tried that test yet, please do. That will help narrow it down to the HAT or something else.

We already tried the test, but unable to get the result.
