I bought a panasonic cq-vd5005u from a reputible pawn shop and when i hooked it up it turned on then off and woldn't turn on again. how do i fix this problem

SOURCE: my panasonic cq-dvr909u wont turn on

pink wire should be ignition, and black one is ground, black one should be comin out of the external amp and the pink one should be on the side of the deck i believe, also yellow one should be next to the black one thats your 12v constant, yellow pink and black should be all ya need to get it to turn on atleast

You need the remote control that goes with this DVD player to make it work it has two security devices. One you remote, you must push the power button on the remote the first time you use it. Two the security code, it is a four digit code that must be entered anytime that the device is installed into a different car. If it's code is not setup yet the code is 0000, otherwise you need to get the code from the person that installed it. There is no way to bypass the these two steps.
