I have Samsung TV model UN55JU65000 FXZC. It is little over 4 years old. One day it suddenly shut itself off, and would not turn on, but standby light kept flashing. A TV repair tech said the SMPS has failed, and he said he has replaced it. TV worked fine for a month and then exactly same thing happened, perhaps SMPS failed again.
Why would this happen,? Is there something the repair tech is missing?
I would highly appreciate an opinion to guide the tech.
Thanks
