I too experienced the dreaded melted 12v plug. TV worked great for a year, then last week I started having intermittent power issues with it. I thought the springs on the plug were getting loose as it would power up again if I rotated the plug in the socket. It finally occurred to me to pull the plug out and look at it. This is what I found.....
Fortunately because of this thread I had a phone number to call at Jensen (ASA). I called on Tuesday morning and UPS dropped off the new plug today. ASA has redesigned the plug so it has a metal tip that won't melt...at least not at the temps that the plastic one did...and made the whole plug portion much smaller. Very quick service, thank you Jensen and thank you for standing behind your product with customer support. I thought about getting a 110 to 12v converter to plug in for power but hopefully this replacement plug will solve the problem.
