If you haven't recently changed to demo mode, or some how activated the sleep feature, then I would say that either the power switch or power supply have gone south on you. I would wager that the power supply has a bad capacitor in it some where. if you are pretty tech savy you can take it apart and see for yourself as the bad capacitors are usually swelled up. also there is usually more then one. but not more then three.

Toshiba tv won't turn off/ stay on

Try unplugging your television for a half an hour or so. It might reset to original settings, Your problem might be input lock features. If you can get to the menu after unplugging your tv for awhile we might be on the right track. I'm just looking thru a Toshiba manual that I have.

The tv usually turns on but all of a sudden it won't. When it does turn on it makes a loud noise like a boat. Someone told me its the fan but I'm not 100% sure though. The noise stays on until the tv

Sounds like the motherboard on the TV has failed. Would recommend replacing the TV or taking it to a TV repair shop which may cost more than just replacing it.

Won't Stay On TV MODE.

What I need to know aside from brand and model number is does the set have a button that changes this feature or the player?

My samsung LED TV turns on sometines and other times the red light stays on and won't respond to remote control

leave the tv disconnected for a while because if you keep messing with it like my kids did and it will cause the bulb inside to burn out and will not even be worth fixing
