PN64E7000 here... same issue as others on the forum. About a month ago it started shutting off randomly. Sometimes I can unplug it and flush the power from the boards and it will work for a few hours. Other times, it won't come back on at all.
It was purchased in Nov 2012... so not quite 2 years old.
I followed the advice of some others on this forum and called the executive support line. My interaction when as follows:
1 - Call Executive support: "Sorry, we can't do anything"
2 - Transferred me to gen-pop tech support
3 - Gen-pop tech support: "Unplug it, do firmware update, sorry you need to buy a warranty"
4 - Transferred me to warranty sales
5 - Warranty sales: "Sorry, we don't offer extended warranties on plasmas"
6 - Me: "I'm mad, I demand to speak to a manager in executive support"
7 - Transferred to a different Executive support line
8 - Executive support: "Sorry, nothing we can do"
9 - Me: "Pretty please" (and lots of complaining)
10 - Executive support: "Ok, we'll do a one time repair for parts ONLY"
So I dropped my TV off at a local repair company. I will be responsible for labor only, parts should be fully covered. I do not know what they would do if it were something huge like a faulty panel. I also hope they test it extensively, because the issue is so intermittent.
I'll update this thread once I get my TV back. Fingers crossed!
