Common fault in the power supply, does the screen flash light for about a sec before it turns off?

Tv powers up but goes directly into stand by mode


An Electronic component has failed. Unless you can repair circuits, take it to a shop or friend who can. Consider cost of replacement. A few hundred will fix an old tv, a couple more and you have a whole new unit.

Sylvania 6842THG won't turn on. the tv red light displays when you push the power button you hear a click and then 5 - 10 seconds it goes back off


I have been having the same issue. I unplug the TV for 10 minutes and it usually works fine. I moves all of my A/V plugs to a single power strip and that helped a lot. Since then, the TV went into protection mode only once in 2 weeks. Next, I will use a power strip that includes the cable protection.
