Repair of cd-player
 

I have made a mistake! Well, probably...:(
I was so kind that i have took my mothers Aiwa radio-cd-tapre recorder to clean it inside-out. Well, after that the cd wont read cd-r! It was doing fine before and it did not had any problem reading any kind of cd-s. Now it reads only originals. :cannotbe: What might be the fault? The lens is clean.
When i put cd, player trys 3 times to start spinning the disc but stops after it. :xeye:
The thing is that the same model she has on work which works fine, and reads every kind of cd, including cd-r.... That one i have not "cleaned" :smash:
Both units were bought in a same store within 1 month.
