Hello WendyOreo,

 

It sounds like your switching power supply or you High Voltage power supply has malfunctioned. These sections control all power to the TV and can produce the situation you are describing. If you do not have a background in electronics, I would suggest that you have a TV repairperson come over and check your TV out.

 

I say this because there are voltages in a TV set that can kill, so caution is needed.

 

I hope this helps

Thank you,

Shuttle83

Model 55sl417u. Why doesn't it turn on?


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

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.
