Dyson DC 25 wont turn on

Why does your daughter think that? While a whole house surge protector is something I can't recommend enough, it's highly unlikely that the average power surge would take out a vacuum. The usual suspects are not plugged in all the way, the filter has never been cleaned, the cord has a tweak, break or is exposed somewhere or the vacuum's fuse blew (if it was a power surge, that's where you'd want to look.

Your owner's manual should have instructions for changing the fuse, if not, take it to a certified Dyson service store and have them check the fuse for you. :)

My lg 37lh20 model wont turn back on.It cut off when circuit breaker blew a fuse.

Sounds like a power surge hit your TV. Typically when this happens capacitors on the power board with blow. You can buy a repair kit for this problem from several of the dot coms out there. The best one I have found has been tvrepairkits .com. Hope this helps.

My tv wont turn on

Here are some DIY steps that may help you fixing the problem.

We had a power surge in our living room while the TV was on. It was also plugged into a surge protector, however, everything else turned back on but the TV. There is no power going into it at all, as if...

Sounds like it might have blew a fuse on the AC input to the power supply, have to remove the back and look for a fuse near where the AC wires go from the plug on the tv. If the fuse is good
the power supply board will have to be checked or replaced..Next time consider buying a surge
protector that starts clamping at a lower voltage. Panamax brands usually start going to work
at 150v rms, where most others start at 330v rms..

My tv wont turnon after being off n unplugged for 6 months what should I do. Sony kdl32l5000

First lets try the basics...
1 check the AC cord for flaws
2 try plugging the TV in another wall outlet (always use a surge-protector) then try powering the TV on again
3 plug tv into surge protector, plug into wall then find the house fuse box going too that outlet and turn it off & on once. Then try powering the TV on again.
4 it could also be the ac fuse inside the TV that blew from the TV's last usage.
If its been in the cold or in excessive thermal conditions for 6 months you could have moisture build up on the boards or warping...
hope this helps, contact me at the link below for further help...

Tv wont turn on

The surge most likely shorted the horizontal output transistor, and with that being shorted, it causes the power supply to "sing" from the increased load it is seeing. Unfortunately, it would probably cost near $100 to repair unless you were able to do it yourself.
