Replacing the stock Roland TD-20/20x screen with new OLED TD1220RDR screen.

Link to the cleaning video:    • Roland TD-20 screen problem repair/fix solved   This worked for a while but my screen started to fail again. Ignore the last picture in this video. A day after installing the TD1220RDR the image of the TD-20 started showing up. Can someone tell me why this would happen? Bonus points for anyone who can tell me where the background music is from!
