Will not stay on...

Hello, with this problem, it's no-doubt that thereis a problem with the circuits or electronics. Most likely you have faulty cables externally or internally, or you may have a short circuit, which is when electricity is taking an 'easier route', when the electricity should be going through the whole machine. Try cleaning any connections between internally and externally. But sometimes, things ar very simple, so first, make sure that the player is firmly and properly plugged in to the power supply.
