I just got off the phone with Samsung support - I was calling to follow up on the ECR ticket I (indirectly) opened this past Saturday regarding power cycling.
Not to get anybody's hopes up yet, but...
The csr stated he seemed to recall an email (may have been a different form of correspondence) circulating (I assume w/i the Samsung support department) that some of their 2008 model TV's were indeed experiencing said issue. He believes the HL61A750 set was on that list...I think his direct words were "...the email wasn't specifically directed towards your model #, it was directed to some of our 2008 TV's."
He furthered stated that...he believes a firmware upgrade is currently in the very early stages of development (alpha?) for the A750.
I tried prying more information out of him but he informed me to call back tomorrow when the ECR department is open (8:00 - 6:00 CST) and I could speak to someone directly concerning the matter.
So...perhaps progress, perhaps an ill-informed customer service representative (no disrespect to him, by any means, he certainly meant well). Either way, thought I would let everyone know.
