translate.google.com may help a little bit with your English.
As far as I can gather, the electricity in your area is not very reliable. One time, it turned off, and turned back on, and your TV would not switch on anymore. Is this right?
A problem like that could be caused by many different things. Perhaps a voltage spike when the electricity came back blew a fuse?
Google translate will help a lot, I think
Good luck!

That would be way too much to post here
What is the model number of your TV? You can usually find service manuals on the internet, that can troubleshoot problems. If you google the part number, you may be able to find one.
Hi John. It probably would have been best for you to start another thread with this question, but it's a fairly quick answer. Usually when I need a service or user manual for an appliance, I simply google the make/model number + manual. If there are any out there online, you'll find them there.
