I have a 2012 element TV that will just shuts off as quick a few minutes or will stay a hr or so but still will shut on its on even though the sleep timer is off

SOURCE: Philips/Magnavox TV, model MS3250C321 shuts off randomly.

TV shutting off automatically means its a problem with the Lamp. Contact Pioneer or any local tech shop or Best buy and get the same replaced.
Turning off after specific time : Go to the timer option and disable the Automatically Switch off option. This will resolve the issue. Please let me know if it worked. If you need the user manual or instruction manula please click on the link below

TV turns on for 2 seconds then shuts off. Sleep/timer blinks. Won't go back on unless unplugged and plugged back in

SOURCE: Roomba shuts down after a few minutes

The brushes are clean on the outside, but probably not inside of the little yellow contact on the end. Also the junk that collects on the brushes finds its way into the gear box. Mine kept shutting down w/ the "Please remove and clean Roomba's brushes" message. I finally gave up and took it apart. There was a surprising amount of junk in the gear box. After I got it apart, I cleaned it out and I even used a straight pin and a pair of tweezers to get all of the gunk out. Now it runs like new. I'm no mechanic, but I used to help my daddy fix things around the house. I posted my solution to the problem and it has worked for a couple of other people too.

Ours did the exact same thing.. I Decided the remote thing was worth a try. I turned the TV to DVD (without a DVD in the player) pressed the set up button (on remote) and Restored the Default option. (Highlighted Default; highlighted Restore then pressed OK) Then exited the set up. I did this twice just to make sure, LoL well.. it's been on over 4hrs now with no problem.. seems like this fixed it.. hope it helps!!

SOURCE: Olevia TV Remote doesnt work Sleep Timer

The TV is in 'showroom mode'. To fix: Click: Menu --> Picture --> Mode --> Power up then select: Home. Then click menu until you exit the settings. You will now be able to use the sleep timer.
