I guess that's the concern. Will the issue get worse or stay the same? I already have issues with the HDMI ports where I don't get a signal unless I turn the TV on last. Not sure if this is related to a power board issue, or a main board issue.This seems to be a very common failure mode of this TV.
For me, having the power supply replaced got rid of it - 99% of the time - but every once in a while I still hit it.
I've learned to just walk away and come back five minutes later and it will power on.
Were it any other TV, I would have returned it, concerned the issue will get worse.
But this TV is just so plain excellent when it's on, I couldn't.
I can live with both these issues. I don't normally turn the TV on 5-10 minutes after turning it off, but i'm starting to wonder where the next issue will come from and whether it's worth getting Samsung to start replacing boards.
I don't want a potentially faulty power board to break something else to point where the TV will not turn on at all!
