How to calibrate cd lens

I have a xr-p170c pioneer receiver. I need to boost up the cd lens. would like to know how …thanks:confused:

How old is that unit? There is nothing that I know will boost that laser it’s set at that power and you can’t change it. You have to open it to clean the laser lens to read and burn better assuming the unit is working correctly otherwise purchasing a new burner is inexpensive nowdays.

thanks for the info…the unit is about 6 years. It is still working well, the problem it is a 3 cd platter and I need the 3 cds to be always on tray for it to function well. When I remove the upper cover of laser, adding some light …nomore problem ,
