Lid Won't Close
You push the lid down, but it won't snap shut.
Missing/Broken Locking Clips
Check to see if two locking clips are on the underside of the lid. If one or both are missing, you could replace the lid. A less expensive alternative would be to replace the clips with a similar sized object, or even stick a pen inside the holes to trick the device into thinking it is closed.
Battery Charging Issues
You plug in the charger, but the battery does not charge.
Make sure the outlet you are using has power by plugging something else into the outlet. If the outlet is functional, it could be a defective charger.
Broken Battery Jack
If the battery jack is loose so the charger does not fit correctly into the device the jack to be replaced.
If the above issues all seem to be fine, battery itself may be defective, and a new one might need to be installed.
The player turns on but nothing shows up on the screen.
Sometimes the system freezes, and all it needs is to be reset. Trying turning the device on and off, and see if that solves it.
Screen Ribbon Cable Problem
Check the ribbon cable connecting the body of the player to the screen. It may be disconnected or broken. If it is disconnected, reconnect it. If it is broken, you will need a new ribbon cable.
If the above options are not the issue, the screen itself probably needs to be replaced.
A button gets stuck or is unresponsive.
Dirt in the Buttons
Sometimes when the buttons get dirty, they no longer push in. Clean around the side of the buttons with a cotton swab to remove dirt.
Disc Won't Read
You put the disc in and an error message is displayed saying "disc won't read."
Try cleaning the disc. If the same message occurs, try using a different disc. If no disc will work, it may be an issue with the player rather than the disc itself.
Clean the Laser Lens
Open the lid of the player and clean the laser. To clean it, wet a cotton swab with isopropyl alcohol, and rub the laser lens very lightly with the cotton swab in circular motions. Be careful not to touch the laser with your hand. If the error message occurs after the laser has been adequately cleaned, the laser should be replaced.
The video freezes while it is playing.
Shut down the device so that it can cool off for while. If the environment around the device is hot, the device will overheat more easily, so try to use it in cooler areas for the best performance.
If the disc is dirty or scratched, this may cause the freezing. Clean the disc or try a new disc. With scratched discs, the best option is to get the disc resurfaced.
