My sylvania portable DVD player won't read discs the display says No Disc after the spin. What do I do?
I had same problem with a sylvania portable DVD: no disc.
After cleaning the laser didn't work, I took the unit apart, and found that there is a small gear that moves the laser back and forth across the disc.. The gear could easily be misaligned with a rough bump along the drive.. All I did was realign the gear to the center where the disc was. Inside, there was even a small lever to pull back on to do this..
I also noticed a small Ribbon cable connecting the laser to the main board. Again, seemed nimble. I detached the ribbon, cleaned the connectors with alcohol and reattached.
Happy to say, it works perfectly now. :). Good luck.
