Today my power went out for a split second and came back on I turn my TV back on it makes a high pitched whining noise and the screen wont turn on. Cant add picture but model number is MW30G71.


unplug your tv. let it sit for a good bit. 1/2 hour did your power just go out or did you have a power surge then no power. surges cause the grid to go down for a second too and that causes problems too. surge protectors are good for everything. also are you on cable? if so have the cable company check they're filters into the house may be an issue but check the tv after a half hour unplgged and then plug in and turn on normally? sometimes it needs a reset time period before the fuses inside will reset themselves.

Potentially so, however I would get the TV fully checked over by a professional if it has been subject to a surge. If a component further down the line caused the initial surge replacing the blown cap will only result in another bang as soon as you plug it in.

Model # P18004W01B wont turn on after power failure even though it was plugged into a surge protector power strip.


Power surge protectors don't always work 100%.
Hopefully the TV has internal Diode protection and it can be fixed cheap

Samsung LE32A4566C2D flat screen tv wont turn on?


There is a chance the power supply is fried. However, I've seen some Samsung power supplies that have fusible resistors in the power supply for added protection. So your main fuse could be ok, but there could be an additional fusible resistor in the board as well. Also be aware, depending on where the surge entered the TV, you could also have a defective main board. Not trying to rain on your parade, but surge damage can sometimes be severe.

I turned on my tv this morning and it started smoking and of course smelling like something inside was burning. We took off the back and can see nothing that looks burnt or melted but the tv still wont...


hi,
may be ur tvs lamp side have some problem. may be the lamp over heated and burned. just open its lamp cover ann check it.
also check its power supply input point(near fuse) there is an MOV (used for voltage surge protection) is burned or not. if there is any voltage surge it will get shorted and the fuse will blow off, protect the power supply for any further damage. check the fuse also. if found open then check the MOV. insert fuse only after replacing the MOV.
ok

TV Wont turn on after lighting storm. I have tried to; unplug and plug back in. Unplug it for 24 hrs. Try different outlets. Look at the build, looks fine.


The TV circuitry is designed to protect from power surges. The fuse on the power supply may be blown, or the power supply itself could have taken a hit. I would try to check the fuse first and then if it turns back on... it did it's job!

Good luck! and let me know what happens!

Tv does not turn on after a thunderstorm and several attempts at power returning to the home. The power went on briefly then shut off several times, now the television will not turn on. We had the tv...


Check the main fuse in the power supply, the TV also has small surge protection devices (MOVs) installed after the fuse, any surges the come along and big enough will cause the main AC fuse to blow. When you surge protector, EVERY connections must go through the surge protector, for example, the AC cord of the TV is connected to the surge protector, the cable connection did not go through the surge protection, the surge then can get to the TV through the cables.
