I turn on tv and two second later it turns right off. no picture when this happens


I have the same exact TV and the same exact problem it seems pretty popular, but there also seem to be different answers to similar questions. Some sort of problem with the Power Supply Unit. Maybe a blown fuse or bad capacitor, thats what i am about to check for, ill be coming back here in hope of finding a solution.

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.

Sylvania 42" flat screen won't turn on


First you should check the fuse and the wiring in your tv by removing the back cover. Make sure no wires are bare or touching. If there are any, wrap them with electrical tape.
If you cannot see anything wrong by looking, then it is probably the set has a bad transformer (high voltage)

After i turn on tv- it turns off right away by itself


That board has the Sylvania part number 1EDM10583 and the price is about right. It might also need some adjustments after installation. Sylvania has no circuit diagram for that board. The TV was assembled by Panasonic and also was used in a Magnavox model. Panasonic may have had the power board designed and made for them by someone else. A technician would have to have some very good luck to repair a board like that without a schematic. Sometimes board rebuilders like PTS have the capability of repairing a board like that. You just have to ask them.
