I know I'll get hammered for this, but here it goes.........I have a Mintek portable DVD player (I know, should have bought another brand). Anyway, it will recognize a disk, but it stays in the loading mode with the disk spinning at high speed. Never starts what's on the disk. Any possible fix, or suggested problems that may be causing this (except buy a different player)? Thanks group.
Thanks for the reply. It plays a music CD fine. I figure since I don't get the "no disk" message with a DVD, the laser is OK. I did notice that if the laser is moved away from the center, then put in a disk to play, the laser doesn't track back to the center - it doesn't move.
If it plays a CD ok, then the sled must be capable of movement. If the laser genuinely doesn't home when a DVD is put in there, then that is a puzzle. What happens if you deliberately move the laser from home, and then just shut the door? Likewise, if you do the same with a CD? In all cases, the laser homing should be the very first thing that occurs, as soon as the system control micro detects that the door switch has closed. That aside, you cannot infer that the laser is good, just because you don't get a "no disc" indication. If the disc spins up, that implies that focus has been correctly obtained. The reason that it then continues to spin at high speed is that the spindle servo has not locked. This can be for several reasons. However, the fact that a CD can be played generally indicates that the servo and motor drive circuitry are operating correctly. By far, the most common problem when a CD can be played, but a DVD not, is the laser ( optical block ) itself.
