I need to replace the power cord

it had no cord because it was no good
it probably could be fixed but the cost would exceed a new one which is probably what the original owners did

Your Tv possibly have faulty y sustain board, just replace that board to fix the problem

Take the tv aparts.The tv power supply board,that the board,have power a/c cord plug into it.That the power supply board,check component parts like capacitors,see if it leaking gases,these capacitors are dead.Capacitors they'll alway bulges up on it tops or puff up on it tops.Have tools like soldering iron and solders?Know basic electronic and soldering?Replaced these dead capacitors will get power to ur tv back.Or tries websites like Shopjkimmy.com to buy a whole refurbish power supply board for the replacement.

Looks like SMPS circuit problem. Contact authorized service center.
