View Full Version : CD-ROM head humming, won't read discs.

I have a Toshiba XM-3401B caddy load drive that will reject any disc inserted.
Upon removing the (die-cast) lid from the drive, I have discovered the coil that focuses the laser is oscillating. As soon as the drive gets power the head is retracted fully, and an audible high pitch noise is heard.
Anyone repair one of these before? I'm probably going to start with washing the board in case any capacitors have leaked. The gearing for the eject mechanism and for the laser sled positioning seems to be OK, and both motors are managing to operate.
