You get what you pay for... Anything cheap sold at Walmart, really is...
I would never pay $380.00 to get something repaired, if a newer one is only a couple hundred more. Not to mention you can probably find a similar model used, for the same money.
Seems like a lot of cheap electronics carry that same "mis-use" clause in the warranty, and I avoid those items, as I'm pretty sure they already know there are design issues.
I'm more concerned with functional repairs, then what makes it look new. My solution most likely would have been a socket dangling outside the case. Total cost, maybe 50 cents, if I had to buy the part, but likely have something laying around that would fit the plug, or clip the wires and use something else...
