my rope lghts start out as 120 volt 0.15 amp ac and is stepped down and converted to 12vdc 1.6 amp.

ollies have the replacement power cord but no rope lights.

I'll bet it is the wiring or a bad manufacturer. The overheating people are talking about is how LEDs are amp hungry. They will suck as much amps as they can get and overheat until the basically melt. This shouldn't happen over a long period (days) of time but more like hours or seconds even. I'd check the application and if there is a broken wire in the string of leds before anything else. That is the more likely culprit. Check the other thread for further thoughts.

+ rep for this one.
Don't dismiss this idea folks. I've seen this done before It's very effective, since the light distribution is ideal. And it requires lot less light, since shadows are almost non-existent. With LED Christmas lights, you're looking at serious MTBF numbers. And it works outdoors too (think extended picnic hours).
