you can fix this by using a pc to finalise the disk
open likes of nero and tools and disk info and close disk
the problem can also be mechanical
i repair stuff like this
i have one here
it seeked and found either bad info or not the right loader info
i suspected a bad batch of laser diodes
as the head output is low
but it was the fet amp on the head was the problem or the solder connections to the leds
due to bad solder type {its a old style lead free build}
or mechanical wear thru vibrations
so a very quick 12watt solder iron very fine tip {antex type}
to the pins {slowly}
fixed its output and it now reads any disk
the original symptoms were not reading any but recorded disks
then after 6 months no disks at all
this would ring true as a recorder recorded disk
is known to give higher mechanical clarity than a bought disk
but not nessisary better quality this depends on the recorder bits rate etc... but a higher output level of transistions as it reads the dots
so check the head and resolder the 8 pin chip and all led connections on it
and it will work i think !!!
