3 pin male to RCA male plug. surely audiovisual related ? do you know for which equipment ? thankss

Need some advice, this cable is for my electric standing desk one day the control box lower and got smashed by the arm rest of the chair and the plastic casing around these prongs broke. For a while I used pliers to straighten the prongs and it still worked but now it’s not working at all. The problem is the opposite end of the cable is directly connected to the mechanism that makes the desk stand and it doesn’t unplug from that end. Can I cut this male end and strip the wires down and reconnect a new stripped male end? What would be the easiest way to fix this. I have very little experience stripping and taping wires but I’ve done it once or twice ten years ago.

Tv is a lg65qned92aua and everywhere tells me it only uses c7 or c13 cables. The only one I can find that looks like it is the iec c9 cable. Is this the correct one or am I wrong? Yes i know its dusty
