kasun,hello！
I want to know, the change inside the laser head laser diode, is not required by the electron microscope, to replace and install a good laser diode, let the laser diode by corresponding voltage and current, let it shine, and then install the laser receiving circuit (almost transparent chip), then with the aid of the installation position of the electron microscope for adjusting chip, is that right?

kaosun

You're right.

Kaosun Hello！
I have a question:
I aiwaXP-77 when playing. If the machine is inverted, the voice will intermittently. This phenomenon is produced with the rotation speed of the disc, and will appear in the headset inside (sand rustles), this sound is, and the speed of the CD synchronization, and very easy to come to a halt. This is what causes?

Have you replaced all leaking SMT capacitors? If no, just do it.
