Search the site by type in the "Brand Name" (Exclude the model number) to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

go to start menu, find the search bar and type in screen saver. If that does not work then go to control panel, Personalization or display and find screen saver. There you can adjust the time when it will kick on.

Does the OSD (on screen display) come up when you hit the menu button? If so try changing the input to the one you need.

You might want to check your rollout switch on the burners it may be kicked.It will have a small red button on it .Push it in to reset

I have the SAME issue and so far it seems to be an issue with the fan not kicking on.... I turn it on in the morning, as soon as you hear sound the red lights kick on and I shut it off... it takes a few seconds to shut down so stay close to your remote durring this process and as soon as the "red light" kicks in, turn it off, as soon as it's off, turn it back on... I have to go thru this about 30 times now before I can get the picture to stay on, but it eventually kicks in. Hope this helps!

good day, maybe your tv has a defect. you need a qualified technician t o fix your problem.

need screen

try replacing the memory...

Don't feel bad - these are cheap TV's and there are lots of problems with them. Just be glad it failed so soon that you can take it right back and get something more name brand this time.
Remember - always google the model number you are looking to buy (with either "repair" or "complaint" in the search) and you'll be less likely to buy an TV industry land mine.
