But check lasercurrent: too high is not beneficial. See service manual for right value.They have a long life
Where can I find the service manual? PDF will be good!!!tubee said:

Thanks,

you nend to have a check you servo board under the laser.as i know CD80 may use TDA8808T and TDA8809T.
if that is true.then have a look at the photo.in the right side,17pin,18pin are from TDA8808T.find out the resistance which is 12E connets to LO(11-9) ,output to the laser in the left side.the photo is from CD850.but they are the same.when CDP is playing,try to got the voltage of that resistance.you know I=V/R.
then you will get the current.if current is less than 60MA,that your laser is good.
good luck and to be careful
