A different TM1628 7-segment display

TM1628 is an LED controller IC that's used mostly at DVD players front panels. The IC can control up to 7 sets of segments (separate digits) and can also process input from up to 16 individual keys. It is controlled via SPI compatible serial interface.

The only Arduino compatible library I was able to find for TM1628 is developed by Vasyl Yudin and is available on GitHub. But, I couldn't get any readable output on display. That happened because my front panel had a different segment assignment to the controller than what I found on YouTube (the display with disc icon on it).

My front panel came from TeleSystem TS5.9RX DVD Recorder and it has 7 digits and some other indicator LEDs. The PCB also contains 5 keys - but I can expand it by adding more buttons. Below is a sketch example for this front panel. It is 5V compatible so it can be connected directly to 5V levels development boards like Arduino and compatible.
