My Phillips Portable DVD Player PET824 says it is loading the dvd, the dvd is spinning, but it never loads. The blue screen that says "Phillips DVD Video" remains. I can hear the motor running and it sounds normal but no video.

follow this steps, and fix it. Merry Christmas.
However you must sure if you device can play any CD/DVD.
Does not play disc

1. No disc. - Load a disc into the tray.
2. Disc has been loaded upside down. Place the disc with the label side up.
3. Disc region code does not match region code of the player.
4. Disc type is not the correct type to play.
5. Disc is damaged or dirty. Clean the disc or try another.
6. Moisture may be condensed inside the unit. Remove the disc and the leave the power on for one or two hours.

maybe the spindle motor is defective so it cannot read the disc. just bring that your dvd to sony service center to fix your dvd.

you better take it to someone professional in the domain as your portable dvd player seem to have problem with its laser

could be down to a dirty lens , faulty lens or faulty dvd player spindle motor.

you can try moving the laser lens that reads the dvd's just don't touch the lens just move that little square it's attached. all you have to do is move it back or forth just a little and leave it and try the cd and if that don't work just keep on moving it around until it reads. it'll work i had that problem on my dvd player and my playstation.

the laser may be broken,and can not read...

This may be due to a bad contact in the connector. If you unscrew and remove the back cover, there is bunch of wires coming from the LCD with a male or female, I forgot, connector on the end, which plugs into its counterpart on the main board. That connector may not be fuly plugged in. The chance that this is indeed the case is no more than 10%. Unfortunatey it looks like this the electronics failure - 70% or LCD itself - 20%
