Thanks. Good set of photos. It's having an effect, but not fully fixing it.

When you ran the install script, did you select the "quality" or "convenience" option?

Yes I have seen that option and I have chosen not to solder. So convience option is what I have chosen.

OK, let's just send you another panel and see if that helps.

Send an email to support@adafruit.com with a link to this thread and your order number and they can send you a replacement RGB matrix panel (PID 2279).
