Electronics Repair Questions? Ask an Electronics Technician
Hi , I`m Jack a Canadian fellow and I will be helping you today
First , no matter what you do ,do not open the tv , it is still under warranty and that would void it
What is the tv doing now if anything ?Is there a light or blinking light at the front , clicking sound from inside when you plug in the power cord or try to turn it on ?Or completely dead no activity whatsoever ?
The last question was to determine what may have gone wrong but in any case what you described has nothing to do with some sort of reset and you should be contacting your local bestbuy where you bought it for service
These tv`s are made exclusively for bestbuy and the geek squad does the service on them
