so as an update i think i have a theory on this one. i returned to walmart to exchange the glo. it was not an issue and the electronics rep grabbed me the last one they had. it was black while the first one was white with a red back. the wife liked the first one better. anyways, the rep then escorted me to customer service with it to do the exchange. which was basically a signature and then i walked out. now comes my theory... the first purchase included a demagnetization which i think was unnecessary and fried the internals. the second glo was not demagnetized but escorted to the front and it worked perfectly as soon as i plugged it in. i sure wish i had my 4 frustrated hours back. haha.
