Hard time playing first 4 or 5 tracks

I have a higher-end Sharp Mini (shelf system) that can’t play the first 4 or 5 tracks of any cd with out skipping. After I play the last half of a cd and the unit has warned up, I can then play the first tracks fairly well. This system is about 7 or 8 years old. Could the lazor head be out of alignment? Is there anyone who knows what could be causing this or what I need to do to fix it?

thanks, Rusty
