Samsung tv goes into sleep mode every 10 minutes when i watch digital tv through an app source.. the screen goes black and a moving blue samsung logo pops up, the sound of the channel in the back ground still works, i push any button on the remote and the picture comes back... it is sort of when your pc monitor goes to sleep until you move the mouse.. the tv does this eexactly every 10min, please help it is really anoying..

The device sources and the inputs have not been set to the correct mod.There could be a problem with the TV it's self for it to be turning off like a problem with the power supply for the TV.

Just do a factory reset. To do this, you might have to enter its service mode. But before doing this, make a hard reset to it and check. Unplug the TV from AC mains wall socket, and re-plug it back after 10 minutes or so. If it do not help you, enter its service mode, and select the reset option, go to factory reset and press enter. If you wish to get more details about how to enter its service mode option,http://electronicshelponline.blogspot.com/ check this site, and pull up older posts. Service mode option and adjustment procedure to many brand and model TVs are given in detail. If you need any more assistance, be free to contact by comments.

You can open the VGA cable and connect it again, sometimes there are two or three vga ports behind your cpu, connect the right one. Try it, if not success, change the cable.

ur sister possible turned the sleep mode on.......check on ur remote that is is off......if this problem persist u have to call service to fix ur problem

If it's not showing anything and goes to sleep mode, then did you try to select the proper input from the monitor's on-screen menu?
Otherwise I can't help you unless you are more specific - when does it go black, right away or after 10 minutes of watching a movie for example?...

You probably have some bad buffer boards as well as a bad Y-main bd and or a bad X-Main bd. Have a trained samsung tech troubleshoot the set.

Hi,

Solution 1) Press Hold/Sleep & hold buttons at same time for 20 seconds, This may fix you problem.

Solution 2) Press Hold/Sleep & hold buttons at same time for 10 sec. & then leave only Hold/Sleep button keep home button pressed & connect you ipod to PC, That means you have to bring your ipod in DFU mode (Recovery mode) Check out this video for getting ipod touch in DFU mode http://www.youtube.com/watch?v=bITIiGswjFI

It will ask you for restore. Accept Restore you ipod touch request by itune. Wait for few minutes while ipod being restored.

If my solution help you please vote up me.

you should first check all the cables inside the set to make sure they all are seated properly, check some other sources like a dvd player and see if it does it on a dvd, after that it is probably a defective main board
