Question about Flat Panel Televisions
When I turn the TV on, it switches itself off immediatley. If I am prepared to try again and again it eventually will stay on but this is quite frustrating!
Brought this TV just over a year ago and over the past month have been having the problem with increasing frequency.
SOURCE: Sylvania TV will not come on
if its remote control try pressing no 1 and see if it comes on.alternatively the on and off switch if faulty on th tv,but the remote control should still switch it on.also switch off the tv for 24 hours by completely removing it from the mains and see if that resets it.

There is probably a bad capacitor on the power board, I had the same thing happen to my 42LB1DR after 2 years. T.V. would turn on and white power light would blink, no pictue and no sound. If your'e a diy'er, it is not that hard of a fix. Take all the covers off of the back of the tv(UNPLUGGED!!!), then look at all the capacitors on the power board.
These are the capacitors, look to see if any of them appear to have a bump on the top of them. They are supposed to be flat, you can also tell if one of them has gone bad if there is an oily substance on the metal cover that was removed. If one of them is in question, carefully remove the board, and take it to an electronics store to have them sotter ?sp on a new capacitor. It ended up costing me around $40.00 to have this done. Good luck and if you are not comfortable trying this, than take it to a repair shop, but I was quoted around $450 to take the T.V. in. No Thanks

If you leave the tv unplugged for 2 days (atleast) then plug it back in and try to turn it on and if it comes on its the power supply board. If it comes back on it will probably shut off between 30min to 4hrs and you would have to unplug it for 2 days again. All the power needs to drain out of the tv. If thats the case take the back pannel off and check the part number out on the internet. Not hard to do becarefull touching things the power supply does store a little bit or shock in it. Good Luck.

Testimonial: "while we did not unplug the set, we let it sit for 2 days and we were able to turn it on by the remote & manually....does that still sound like P/S"
Yes, something could have gotten changed.
Confirm what input connection the DirecTV receiver is connected to on the back of the TV. Using the remote, check that the TV has that input selected.
