A little update on a case. I replaced capacitors to new THT, low ESR, 105C.
I cleaned and lubricated again laser runner.
The result is that I have some more CD’s that Beo is able to read. Huge improvement in reading later tracks of CDs.
Also more CDRs are working now, but… There are still some CD that are unreadable very quickly.
IMHO it’ s a feature not a bug 😉
Anyway. Thanks for all your help. I finally can write that my Beocenter 9300 is operating again !
