I am looking to purchase a power supply cord for my Naxa 13.3 HD LED TV.

I have lost or misplaced the power cord to my 13.3 Naxa HD LED DVD television. I have the power cord that will run the tv if I chose to take it on a trip and plug in the a cigarette port a dc adapter I think is what its called. What I need if the power supply cord for home. The power supply cord is a xlr 3 pin din end to go to the tv and is required to have a 12 volt 3=a 24 mhz power supply cord. I have reached naxa.com and many other sites, but cant find a 3 pin end. I can find a 4 pin and anything above that. Can you direct me to any company that may be able to help me purchase a 3 xlr pin power supply cord that I can plug the tv into my home, a 110 outlet to be able to view it while home. I have the original box to the tv and it came with both cords for ac viewing and dc viewing, but like I said I lost or misplaced the power supply cord to plug into my 110 outlet for use at home. I look for to any information and help. Thank you. Kristi.
