sony deck CDX C7050X

my sont deck only wants to read some real cd good but not all. whne i put in a cdr it take a while for it to start playing if ever, when it oes does play a cdr though it skips even if the cd has been freshly burned im gonna change the laser right now to see if that has any avail but if any has had this problem please help me out thanks

i fixed it. it wasnt the laser it was the top presure plate spring the arm that puts pressure on the cd so the bootm mount can spin it
Apearently it was loose and the motor wasnt spinign the cd properly so it wouldnt read them right!
