Mp3 player cannot pget power on

First, make sure that the MP3 player's (internal) battery is fully charged. Then unplug it (the MP3 player) from the power source and try to power it up. For some MP3 players, you may have to hold down the "power on/off" button down for a few seconds ... or lots more ... until it reboots (light up) and start up.

1. See if you have a power switch on the side of your MP3 player. If your power switch is on the side, slide the switch up to put it in "Play" mode. To turn the player off, slide the switch up and hold for several seconds. If your power switch is not on the side, proceed with step 2.
2. Look at the top of the Coby MP3 player. Many Coby players that support video have their power switch on the top. Some are in the shape of a bar, and some have a small round button. If you have a bar switch, slide the bar to the right to turn the power on. If you have a round power button on the top of the player, press and hold the button until the player turns on.
