Apex DVD Player model AD-1110W

Hi,

I have an Apex DVD model AD-1110W in my shop for service. Note: I seldom service DVD players. When I insert a DVD or CD, the message says, "Loading" and after a small delay, "No Disc".

I cleaned the optical pickup lens even though it looked clean.

When I insert a DVD or CD, the optical pickup slides in and out, but the disk doesn't spin. I checked the motor for freedom of rotation. I checked voltages from the power supply and all were good except

+12V & -12V which measured +11.17 & -11.07. I "scoped" all the voltages to check for ripple or noise, but all were "clean".

Is it possible for a DVD player to check for the presences of a disc simply by the reflection without rotating the disc?

Thanks in advance, Brad

I suppose it could check for a disc first then spin it to check compliance.

Yes.... the laser checks for a reflection and tries to focus on the disc, if successful the motor will spin. Disconnect the wires going to the spindle motor and use a small 9V transistor battery to power it .... if it doesn't spin, the motor is bad. You can go to the website for this newsgroup at
