What charger do you have?
What "everything" have you tried?
You may or may not need a new charger, but saying "the light is blinking, help" pretty much without more details and then saying "I've tried everything, I need to
buy a new charger." Again without info is going to make it very hard for anyone to help answer your question.
I'm not saying you
don't need a new charger either, but I have generally found the "collective knowledge" of ECF to sometimes be of more use than "Here is no information please help." While ECF is pretty awesome there aren't any mind readers (that I know of) so really in case you
don't need a new charger, tell us what you have, what went wrong, and what you've tried. Worst case, well, you'll
know you need a new charger, best case, someone might have a simple fix for you.
Good luck, but do give more info if you can. Etc.
