I had the same issue. Turned out to be a blown capacitor on the power board.

Yes,replaced all the boards that related to the power supply.Useally completely dead,it effect all the ICS in the boards,never able to tell which boards.U are not a tv tech.don't do this everyday's will not have skills or any idea which board is dead.
it sounds like one of the boards are going out I would call sylvania and check with there service dept maybe they can send a tech and part out under warranty
The most likely the TV has a power supply related problem. The most common thing to go out is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board. I can't say it's 100% the problem because I can't actually look at the tv over the internet. If by chance the TV is still under warranty, go that route. If not under warranty and If you have some electronic experience, you can purchase a Service Manual over the internet and diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists. Usually, cost under $20.
your transformer on your power supply is bad, i would recomend replacing the power supply, usually when the transformer goes bad , it damages other things on the board, should be around a 200$ part
Finally I have managed to fix my plasma 6842PEM. My problem was the SS (Sustain) Board and not the Power supply. This board is the vertical one to the right connecting to the Screen/Panel. I tested every component on the board and found one of the Transistors on the heat sink was bad, part # 2PG001. This board is made by Panasonic which can be replaced. I got the Transistor which only cost $20.00 including shipping.
To identify wether this is your problem, disconnect the cable comming from the power board and put on the TV, If the green light stays on then this is your problem.
Have fixed a bunch of those as a Sylvania ASC. There is a small ceramic capacitor on the main power PCB that has ruptured. It must be replaced with a different part, a special type of capacitor, or it will just fail again. Sylvania had recommended replacing the main power PCB rather than repair because sometimes there was additional damage on the board, however replacing the capacitor fixed every one that came to us. I preferred that because some electrical voltages have to be adjusted if the circuit board is replaced with a different one.
same problem,where can I gt the parts to do it myself
