Reply to Omnitronic Dss-2 Music Stoping

Hey i got Omnitronic Dss-2 i changed the lasers in it cuz it was lagging (the music stops for about 1 sec) and the monitor that displays the time was lagging (stoping the time) too. After i changed it i get the same effect as before the music stops for a sec and then keeps on playing and it does that after 20sec or less . Need help asap thanks
