After a power outage, the tv wont turn back on. was hoping there is a fuse that may have blown.


Hi Michael,
Yes there is a fuse in your TV too and sometimes you do escape with a blown fuse after a power outage. Please open if you can the back cover of your TV, locate the fuse. If you do not see any damaged or blown parts, replace the fuse with the same rating. If the works, enjoy watching. If the fuse blows again, the power board needs to be repaired or replaced.
Good luck.

Watching the TV and heard a "pop", it went dead. Opened up the back and found a blown 4A 125V fuse. Replaced fuse and plugged in TV. Fuse blew instantly when I plugged in the TV. Sylvania...


The power suply unit may be dead......if the fuse blows instantly it means that the main input is short.
possible parts damaged :the diodes from the mains, the power tranzistor and the ic from the primary part and other components around them.
First unplug the tv, unload the mains capacitor (using a light bulb) check all the diodes from the rectifing bridge, check for any shortened semiconductors or blow resistors.


BE VERRY CAREFUL !!! THERE IS A RISK OF ELECTRIC SHOCK ,IF U DON"T KONW ANY ELECTRONICS TAKE IT TO A SPECIALIST

Watching program, heard a pop snap and unit lost all power. Even the vizio logo on front panel is dead.


Seems like a filter capacitor has arced and blown a fuse or a couple of fuses. Open the back cover and check the main fuses. If you replace with new fuses and the TV keeps blowing the fuses then replace the bridge rectifier and main filter capacitor. A local repair shop could take care of this very quickly for you. Its not an expensive repair...

Heard a pop then screen went blank. Now TV wont turn on.


Sounds like your fuse.

If not the fuse in your plug, then the internal fuse in the TV. to get too this you need to open the TV by taking off the back plastic panel and look at the fuse.

the fuse is the glass tube on the board, will no doubt be near where the power cord connects to the TV. and are easy to replace with another fuse. you will know soon as you open it if its blown as the little glass tube will be blackened or the little wire inside the tube will be missing or severed.

Fuses in TVs are actually designed to blow over time with ware (usually to last a bit longer then the warranty time frame) so after the cover has ended the TV can go in for repair work at extra cost. Its a little known fact.

I have a 42 inch ILO Flat Screen TV that is only about 3 years old. I was watching it the other night and it just went dead on me. Any idea what happened and is it fixable?


sounds like an ic chip went out possibly a what is called a mosfet but can't be sure unless I saw it could always be a blown capacitor as well but not likely. I have a 42in philips lcd and it did the same thing I knew it was the power supply but when I looked at it there was no obvious problem after blowing a few fuses to isolate the problem by taking out all the ics and then putting them in one by one to see when the fuse blows i came to the conclusion that on ic the mosfet would blow the fuse i orderded the part online for like $7 including shipping replaced it and now everything is working like a charm. I live in oregon if for some reason you are as well I could always take a look at it for you.

Blown Fuse


If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.

If it went dead a few seconds after pressing the Start pad, that's usually a failing high-voltage transformer.

If it goes dead or blows the breaker when you plug it in or open or close the door, then there's a problem with a door switch or door switch mount.
