RE: Sharp 40-inch Aquos TV keeps turning itself off.
Posted by Dave Pogue on September 13, 2014 at 12:27:55:
I really appreciate your response. Here's a little more info, but I have to say up front that I'm too technically illiterate to perform the tests you suggest. I don't watch it all that much as I'm mainly an audio guy (audio system is completely separate, in another room).
The Sharp is a two-year-old flat screen unit that sits atop a stand. Lots of air circulation. Connections (mostly HDMI) to a nearly new Denon receiver, Oppo Blu-ray/DVD player, an Apple TV, a Comcast cable box and an ancient VCR. No timer. Everything works fine, no problems, except when the TV dies (screen goes black, pilot light goes off). Sound stays on, because it's provided via the Denon receiver. Turning the Sharp back on, it operates as before. Until the next time. The Sharp has never turned itself off more than once in any given day, usually after playing for an hour or two.
After this happened a couple times, I checked the entire unit for any hot spots. Nothing was ever more than mildly warm. Checked repeatedly for bad connections (including AC) and never found any.
Because the problem is so intermittent, I'm now of the opinion that it needs to get worse before calling somebody knowledgeable for help.
