SOURCE: power button is green - no blinks / no picture / no sound

Unplug it from the wall, wait 2 minutes and plug it back in. if problem still exists, its probably the main pcb.

SOURCE: power led blinks but no picture or sound

Had the same problem myself. Took some doing but I managed to find a service bulletin that I downloaded. The problem is with the siene module and all you need to do is unplug connector JP63A from the main board and your TV will work again.
Take the back off the TV (there are a lot of screws) and look on the left hand side of the main circuit board that is mounted in the center of the TV. You will see a small white connector that is labelled JP63A, simply unplug it. Plug the TV back in and let it reboot. That's it, should be able to watch immediately.

You have a leaky capacitor in the high voltage section of your tv and it will eventually fail completely if not replaced. This is not an expensive fix $50. ballpark

My Toshiba 55SL417U will not come on. The led light blinks, but screen remains black. It is no longer under warranty. Is there something I could do to fix it?


Hello
The main board of your TV should be troubleshooted. It is a very skilled work, and you must have sufficiant knoledge in electronics and expereince to work with digital printed circuit boards. In most cases, the repair to this board will be immpossible, and may replace it as card basis.
This is the picture of the main board to your tV.2_4_2012_6_28_32_am.jpg

TV has gone into "protect mode" to do just that to protect against the damaging failure that has been detected, you will need a servicer to diagnose the failure. Good luck and Merry Christmas!

More then likely your power supply failed. If you do not hear a click from the relay during the power up cycle then your power supply failed.

No power


It sounds like the backlight or an inverter board on the television may have failed. Check your warranty status on the television to see if you can get it repaired by the manufacturer for free.
