Arduino - Without Wiring Reusing LED Display Of DVD Player
The project uses no wiring maybe one. I have simplified it for Arduino

DVD Player LED Display Recycling - Arduino Code
Finding the pin-out and testing a DVD Player LED Display for re purposing it on Arduino projects.
More details about this display and 7 segment LED display basics with some code:

Program 1 :
#include "SevSeg.h"
SevSeg sevseg; //Instantiate a seven segment controller object
void setup() {
byte numDigits = 4;
byte digitPins[] = {7, 13, 8,9};
byte segmentPins[] = {0, 1, 2, 3, 4, 5, 6, 15};
bool resistorsOnSegments = false; // 'false' means resistors are on digit pins
byte hardwareConfig = COMMON_ANODE; // See README.md for options
bool updateWithDelays = false; // Default 'false' is Recommended
bool leadingZeros = false; // Use 'true' if you'd like to keep the leading zeros
bool disableDecPoint = false; // Use 'true' if your decimal point doesn't exist or isn't connected
sevseg.begin(hardwareConfig, numDigits, digitPins, segmentPins, resistorsOnSegments,
updateWithDelays, leadingZeros, disableDecPoint);
sevseg.setBrightness(90);
}
void loop() {
static unsigned long timer = millis();
static int deciSeconds = 0;
if (millis() - timer >= 100) {
timer += 100;
deciSeconds++; // 100 milliSeconds is equal to 1 deciSecond
if (deciSeconds == 10000) { // Reset to 0 after counting for 1000 seconds.
deciSeconds=0;
}
sevseg.setNumber(deciSeconds, 1);
}
sevseg.refreshDisplay(); // Must run repeatedly
}
