Extension cord cut outside with hedge cutters, while tv on inside,tripped switch, now tv won't come on

Was it plugged in to an outside receptacle? If so are you trying to plug into it after new cord? Try a different receptacles if you want to be sure go inside the house and plug it in. Try it. If it works. The outside recepticles are on a GFCI circuit an have a test and reset button on it reset it if it does not work check the panel box for a trip breaker turn it all the way off then on again to reset breaker.

Yes, you have a short! It is probably between your neutral and ground. That is why your GFCI is tripping on your outside outlets, but won't trip the non-GFCI breaker on the inside.

The wire into the handle may have been pulled and come loose. You will have to take the handle apart to check. They are simple.

Probably. Extension cords make a BIG difference. Try plugging it directly into the wall.

fuse probably went in the plug/extension-replace plug and mend the cable or replaceit

My Ryobi 890r brush cutter will start and then die

when u say not been used verry much do ya mean it's possible it sat long enough for a mouse or two to make a nest inside the motor? LOL.
seriously tho it sound's to me like the motor just burned out. Personally I would recommend investing in a gas powered hedge trimmer. they last longer and do the job better plus there's no chance of accidently cutting through the extention cord.

you must have blown a fuse. you will have to have a tv technician check it out.

If you are handy, you can do this. Most trimmers some with a very short cord to which you are expected to attach a extension cord. What exactly did you cut? If the short cord that may have come with it ... disassemble the body of the machine and reconnect a shorter (the one you cut) cord. If it was the extension, that is easy. New ends available ar your hardware store.

If there is a trick part,it is in reassembly. Pay attention to how it was configured when you took it apart.

hope this helps

yes it can. you have to slice and solder the wires together and wrap tightly with vinyl electrical tape. if your not familiar with soldering you can have it repaired at your local repair center.
