I don't think I'm too far off base in saying it's pretty much a built in resistor thing.. apparently just not a high enough load built in. Now how complex that becomes to resolve is not my ball park. I have a feeling at this point the only "resolution" they can offer is a refund. Now "knowing" the output on these is totally acceptable vrs another quest .. Well your turn.. LOL
And make it soon since they would probably want these back within a week or so..
