I unplugged the tv set for a few hours and when I plugged it back in, there is an on screen tutorial that goes through the steps of how to program the TV. None of the buttons on the tv will work nor will the remote. How do I get the tutorial off the screen?

first is to hear if sound is there when a DVD etc is connected to one of the rear audio and video inputs on the set.
Also check speakers in the set are in menu switched ON and not OFF.
If a cable box, sat box, receiver are in use check their settings for sound also==not a bad idea to unplug each unit and then after a few minutes plug each back (set , box, etc) to allow each to try to boot up.

This is typical with many sets when it goes old as there is a high possibility that the components over a period of heating and cooling , tend to bring on a problem of dry soldering. So my advice is to check the set for some loose joints that have played on to give you these erratic shut downs.
Remove main plug, the covers - with caution of high voltage, check for dry joints, use a good soldering iron to solder all suspected points. Please find below two links for tips on poor start ups, as if the set is totally failed the SMPS might be faulty.
A temporary solution is to unplug the TV for a few minutes, remove static from the glass with your hand. It is important to unplug rather than turn off. If you have a degauss button you can also press that before unplugging. Wait several minutes or an hour. Then plug it back in. If you have Picture in Picture it may be an issue with that and to permanently solve may need a repair person. The unplugging may get you by for a few days at a time. That's at least better than an hour.
Sounds like a bad digital board to me. Not too hard to replace in those models but, you do have to write down a few settings before replacing it. These settings are available in the service menu. Any questions let me know [email protected]
